Subject: [PATCH] tmpfs: Decrement i_nlink correctly in shmem_rmdir()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=86bc843a268058df558844b6bf64531617fbc698;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] tmpfs: Decrement i_nlink correctly in shmem_rmdir()

shmem_rmdir() must undo the increment of i_nlink done in
shmem_get_inode() for directories, otherwise at least
IN_DELETE_SELF inotify event generation is broken.
