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.
