From 79ddbfa500b37a94fa7501e65ebdd5c0e4c7592d Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 25 Apr 2019 14:26:51 +0100 Subject: afs: Implement sillyrename for unlink and rename Implement sillyrename for AFS unlink and rename, using the NFS variant implementation as a basis. Note that the asynchronous file locking extender/releaser has to be notified with a state change to stop it complaining if there's a race between that and the actual file deletion. A tracepoint, afs_silly_rename, is also added to note the silly rename and the cleanup. The afs_edit_dir tracepoint is given some extra reason indicators and the afs_flock_ev tracepoint is given a silly-delete file lock cancellation indicator.
