Signed-off-by: Emanuele Giuseppe Esposito Emanuele Giuseppe Esposito (8): apparmor: just use vfs_kern_mount to make .null fs: extract simple_pin/release_fs to separate files fs: wrap simple_pin_fs/simple_release_fs arguments in a struct fs: introduce simple_new_inode simplefs: add alloc_anon_inode wrapper simplefs: add file creation functions debugfs: switch to simplefs inode creation API tracefs: switch to simplefs inode creation API arch/powerpc/platforms/cell/spufs/inode.c | 4 +- arch/s390/hypfs/inode.c | 4 +- drivers/gpu/drm/Kconfig | 1 + drivers/gpu/drm/drm_drv.c | 13 +- drivers/infiniband/hw/qib/qib_fs.c | 6 +- drivers/misc/cxl/Kconfig | 1 + drivers/misc/cxl/api.c | 14 +- drivers/misc/ibmasm/ibmasmfs.c | 8 +- drivers/misc/ocxl/Kconfig | 1 + drivers/oprofile/oprofilefs.c | 8 +- drivers/scsi/cxlflash/ocxl_hw.c | 15 +- drivers/usb/gadget/function/f_fs.c | 8 +- fs/Kconfig | 3 + fs/Kconfig.binfmt | 1 + fs/Makefile | 1 + fs/autofs/inode.c | 4 +- fs/binfmt_misc.c | 27 +-- fs/configfs/Kconfig | 1 + fs/configfs/mount.c | 12 +- fs/debugfs/inode.c | 171 +++---------------- fs/efivarfs/inode.c | 4 +- fs/fuse/control.c | 4 +- fs/hugetlbfs/inode.c | 8 +- fs/libfs.c | 48 ++---- fs/ocfs2/dlmfs/dlmfs.c | 8 +- fs/proc/base.c | 4 +- fs/proc/proc_sysctl.c | 5 +- fs/pstore/inode.c | 14 +- fs/ramfs/inode.c | 4 +- fs/simplefs.c | 194 ++++++++++++++++++++++ fs/tracefs/inode.c | 108 ++---------- include/linux/fs.h | 3 +- include/linux/simplefs.h | 36 ++++ ipc/mqueue.c | 4 +- kernel/bpf/inode.c | 7 +- lib/Kconfig.debug | 16 +- mm/shmem.c | 4 +- net/sunrpc/rpc_pipe.c | 4 +- security/Kconfig | 1 + security/apparmor/apparmorfs.c | 48 +++--- security/inode.c | 17 +- 41 files changed, 385 insertions(+), 459 deletions(-) create mode 100644 fs/simplefs.c create mode 100644 include/linux/simplefs.h --=20 2.25.2
