Subject: v5 changelog - mmc: Add ioctl to let userspace apps send ACMDs
Date: Tue, 12 Apr 2011 15:52:54 -0700 (PDT) [thread overview]
Message-ID: <alpine.DEB.2.00.1104121544380.8483@peruna> (raw)
[-- Attachment #1: Type: TEXT/PLAIN, Size: 1021 bytes --]
A small fix for a compiler warning. Thanks to Michał Mirosław for
suggesting the solution!
Patch history below:
- v5
- fix 32-bit compiler warning about the 32+64 compat pointer
- v4
- replace postsleep udelay() with usleep_range()
- add cmd_timeout_ms field for R1B commands
- v3
- copy data from userspace before claiming host
- break out copy from userspace into its own function
- verify that caller has CAP_SYS_RAWIO
- rename ``struct sd_ioc_cmd`` to ``struct mmc_ioc_cmd`` because it
applies generally, not just to SD
- make struct mmc_ioc_cmd the same between 32-bit and 64-bit to
simplify compat_ioctl()
- export include/linux/mmc/ioctl.h when you ``make headers_install``
- v2
- make initialization of struct declarations match kernel style
- only allow ioctl() on whole block device, not partition
- remove extraneous printks
- implement compat_ioctl()
- remove version field from ``struct sd_ioc_cmd``
John
