Subject: eCryptfs: Clear i_nlink in rmdir
From: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
commit 07850552b92b3637fa56767b5e460b4238014447 upstream.
eCryptfs wasn't clearing the eCryptfs inode's i_nlink after a successful
vfs_rmdir() on the lower directory. This resulted in the inode evict and
destroy paths to be missed.
