Jeff Layton 5b7e3e9c2c btrfs: update target inode's ctime on unlink 
[ Upstream commit 3bc2ac2f8f ]

Unlink changes the link count on the target inode. POSIX mandates that
the ctime must also change when this occurs.

According to https://pubs.opengroup.org/onlinepubs/9699919799/functions/unlink.html:

"Upon successful completion, unlink() shall mark for update the last data
 modification and last file status change timestamps of the parent
 directory. Also, if the file's link count is not 0, the last file status
 change timestamp of the file shall be marked for update."
