Hello,
Currently, there are multiple variants of internal sysfs removal
functions and the directory removal behavior is a bit weird in that
while it does remove the files contained immediately in the directory
it wouldn't recurse into its subdirectories, even the group ones which
belong to the same kobject.
This patchset restructures sysfs removal path so that there is single
internal removal function which is fully recursive. This will be the
only removal interface in the planned new interface based on
sysfs_dirents instead of kobjects.
This patchset contains the following four patches.
0001-sysfs-remove-sysfs_addrm_cxt-parent_sd.patch
0002-kobject-grab-an-extra-reference-on-kobject-sd-to-all.patch
0003-sysfs-make-__sysfs_remove_dir-recursive.patch
0004-sysfs-introduce-__-sysfs_remove.patch
The patches are on top of
linus#master c2d95729e3 ("Merge branch 'akpm' (patches from Andrew Morton)")
+ [1] [PATCHSET] sysfs: disentangle kobject namespace handling from sysfs
and available in the following git branch.
