* [RFC PATCH 0/2] audit of linux/device.h users in include/* @ 2012-03-05 0:34 Paul Gortmaker 2012-03-05 0:34 ` [PATCH 1/2] device.h: cleanup users outside of linux/include (C files) Paul Gortmaker 2012-03-05 0:34 ` [PATCH 2/2] device.h: audit and cleanup users in main include dir Paul Gortmaker 0 siblings, 2 replies; 6+ messages in thread From: Paul Gortmaker @ 2012-03-05 0:34 UTC (permalink / raw) To: linux-arch; +Cc: linux-kernel, Paul Gortmaker Nearly every subsystem has some kind of header with a proto like: void foo(struct device *dev); and yet there is no reason for most of these guys to care about the sub fields within the device struct. This allows us to significantly reduce the scope of headers including headers. For this instance, a reduction of about 40% is achieved by replacing the include with the simple fact that the device is some kind of a struct. Unlike the much larger module.h cleanup, this one is simply two commits. One to fix the implicit <linux/device.h> users, and then one to delete the device.h includes from the linux/include/ dir wherever possible. The assumption is that this cleanup will not go in through subsystem maintainers in a fragmented fashion, but instead be pulled as a whole.

* [PATCH 2/2] device.h: audit and cleanup users in main include dir 2012-03-05 0:34 [RFC PATCH 0/2] audit of linux/device.h users in include/* Paul Gortmaker 2012-03-05 0:34 ` [PATCH 1/2] device.h: cleanup users outside of linux/include (C files) Paul Gortmaker @ 2012-03-05 0:34 ` Paul Gortmaker 2012-03-05 0:34 ` Paul Gortmaker 2012-03-05 10:06 ` Linus Walleij 1 sibling, 2 replies; 6+ messages in thread From: Paul Gortmaker @ 2012-03-05 0:34 UTC (permalink / raw) To: linux-arch; +Cc: linux-kernel, Paul Gortmaker The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> --- include/linux/amba/pl022.h | 2 -- include/linux/atmdev.h | 2 +- include/linux/attribute_container.h | 3 ++- include/linux/c2port.h | 3 ++- include/linux/cdrom.h | 1 - include/linux/cpu.h | 3 ++- include/linux/cpufreq.h | 1 - include/linux/crash_dump.h | 1 - include/linux/dma-buf.h | 2 +- include/linux/edac.h | 6 +++++- include/linux/fb.h | 1 - include/linux/firewire.h | 3 ++- include/linux/hwmon-sysfs.h | 2 ++ include/linux/hwmon.h | 2 +- include/linux/hwspinlock.h | 2 +- include/linux/ide.h | 3 ++- include/linux/ipmi.h | 2 +- include/linux/ipmi_smi.h | 3 ++- include/linux/jz4740-adc.h | 2 +- include/linux/maple.h | 2 +- include/linux/mfd/abx500.h | 3 ++- include/linux/mfd/abx500/ab5500.h | 2 +- include/linux/mfd/abx500/ab8500.h | 4 +++- include/linux/mfd/pm8xxx/pm8921.h | 1 - include/linux/mfd/stmpe.h | 4 +++- include/linux/mfd/tc3589x.h | 2 +- include/linux/mlx4/driver.h | 1 - include/linux/mmc/card.h | 1 + include/linux/mmc/core.h | 1 - include/linux/mmc/host.h | 1 + include/linux/netdevice.h | 2 +- include/linux/of_device.h | 3 ++- include/linux/opp.h | 1 + include/linux/phy.h | 5 +++-- include/linux/pm_domain.h | 2 ++ include/linux/power_supply.h | 3 ++- include/linux/regmap.h | 2 +- include/linux/regulator/consumer.h | 3 ++- include/linux/rfkill.h | 2 +- include/linux/rio_drv.h | 1 - include/linux/serial_pnx8xxx.h | 1 - include/linux/spi/mmc_spi.h | 2 +- include/linux/wimax/debug.h | 2 +- include/media/media-device.h | 3 ++- include/media/v4l2-ctrls.h | 1 - include/media/v4l2-ioctl.h | 1 - include/net/mac80211.h | 3 ++- include/scsi/scsi_device.h | 2 +- include/sound/core.h | 5 ++--- include/sound/soc-dapm.h | 3 ++- include/trace/events/regmap.h | 2 +- include/trace/events/rpm.h | 3 ++- include/trace/events/writeback.h | 1 - 53 files changed, 67 insertions(+), 52 deletions(-) diff --git a/include/linux/amba/pl022.h b/include/linux/amba/pl022.h index 572f637..9da37a4 100644 --- a/include/linux/amba/pl022.h +++ b/include/linux/amba/pl022.h @@ -25,8 +25,6 @@ #ifndef _SSP_PL022_H #define _SSP_PL022_H -#include <linux/device.h> - /** * whether SSP is in loopback mode or not */ diff --git a/include/linux/atmdev.h b/include/linux/atmdev.h index f4ff882..52c9409 100644 --- a/include/linux/atmdev.h +++ b/include/linux/atmdev.h @@ -213,7 +213,6 @@ struct atm_cirange { #ifdef __KERNEL__ -#include <linux/device.h> #include <linux/wait.h> /* wait_queue_head_t */ #include <linux/time.h> /* struct timeval */ #include <linux/net.h> @@ -249,6 +248,7 @@ struct k_atm_dev_stats { struct k_atm_aal_stats aal5; }; +struct device; enum { ATM_VF_ADDR, /* Address is in use.

Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> --- include/linux/amba/pl022.h | 2 -- include/linux/atmdev.h | 2 +- include/linux/attribute_container.h | 3 ++- include/linux/c2port.h | 3 ++- include/linux/cdrom.h | 1 - include/linux/cpu.h | 3 ++- include/linux/cpufreq.h | 1 - include/linux/crash_dump.h | 1 - include/linux/dma-buf.h | 2 +- include/linux/edac.h | 6 +++++- include/linux/fb.h | 1 - include/linux/firewire.h | 3 ++- include/linux/hwmon-sysfs.h | 2 ++ include/linux/hwmon.h | 2 +- include/linux/hwspinlock.h | 2 +- include/linux/ide.h | 3 ++- include/linux/ipmi.h | 2 +- include/linux/ipmi_smi.h | 3 ++- include/linux/jz4740-adc.h | 2 +- include/linux/maple.h | 2 +- include/linux/mfd/abx500.h | 3 ++- include/linux/mfd/abx500/ab5500.h | 2 +- include/linux/mfd/abx500/ab8500.h | 4 +++- include/linux/mfd/pm8xxx/pm8921.h | 1 - include/linux/mfd/stmpe.h | 4 +++- include/linux/mfd/tc3589x.h | 2 +- include/linux/mlx4/driver.h | 1 - include/linux/mmc/card.h | 1 + include/linux/mmc/core.h | 1 - include/linux/mmc/host.h | 1 + include/linux/netdevice.h | 2 +- include/linux/of_device.h | 3 ++- include/linux/opp.h | 1 + include/linux/phy.h | 5 +++-- include/linux/pm_domain.h | 2 ++ include/linux/power_supply.h | 3 ++- include/linux/regmap.h | 2 +- include/linux/regulator/consumer.h | 3 ++- include/linux/rfkill.h | 2 +- include/linux/rio_drv.h | 1 - include/linux/serial_pnx8xxx.h | 1 - include/linux/spi/mmc_spi.h | 2 +- include/linux/wimax/debug.h | 2 +- include/media/media-device.h | 3 ++- include/media/v4l2-ctrls.h | 1 - include/media/v4l2-ioctl.h | 1 - include/net/mac80211.h | 3 ++- include/scsi/scsi_device.h | 2 +- include/sound/core.h | 5 ++--- include/sound/soc-dapm.h | 3 ++- include/trace/events/regmap.h | 2 +- include/trace/events/rpm.h | 3 ++- include/trace/events/writeback.h | 1 - 53 files changed, 67 insertions(+), 52 deletions(-) diff --git a/include/linux/amba/pl022.h b/include/linux/amba/pl022.h index 572f637..9da37a4 100644 --- a/include/linux/amba/pl022.h +++ b/include/linux/amba/pl022.h @@ -25,8 +25,6 @@ #ifndef _SSP_PL022_H #define _SSP_PL022_H -#include <linux/device.h> - /** * whether SSP is in loopback mode or not */ diff --git a/include/linux/atmdev.h b/include/linux/atmdev.h index f4ff882..52c9409 100644 --- a/include/linux/atmdev.h +++ b/include/linux/atmdev.h @@ -213,7 +213,6 @@ struct atm_cirange { #ifdef __KERNEL__ -#include <linux/device.h> #include <linux/wait.h> /* wait_queue_head_t */ #include <linux/time.h> /* struct timeval */ #include <linux/net.h> @@ -249,6 +248,7 @@ struct k_atm_dev_stats { struct k_atm_aal_stats aal5; }; +struct device; enum { ATM_VF_ADDR, /* Address is in use.
