Subject: [PATCH] ecryptfs: Fix inodes not being evicted until unmount
Date: Fri, 8 May 2020 09:31:33 -0500	[thread overview]
Message-ID: <20200508143131.GA7116@jeffrey-work> (raw)

On asynchronous base filesystems like NFS, eCryptFS leaves inodes for
deleted files in the cache until unmounting. Change call in
ecryptfs_do_unlink() from set_nlink() to drop_nlink() in order to reliably
evict inodes from the cache even on top of NFS.
