Pull fscrypt fix from Eric Biggers:
"Fix a bug where if userspace is writing to encrypted files while the
FS_IOC_REMOVE_ENCRYPTION_KEY ioctl (introduced in v5.4) is running,
dirty inodes could be evicted, causing writes could be lost or the
filesystem to hang due to a use-after-free. This was encountered
during real-world use, not just theoretical.
Tested with the existing fscrypt xfstests, and with a new xfstest I
wrote to reproduce this bug. This fix does expose an existing bug with
'-o lazytime' that Ted is working on fixing, but this fix is more
critical and needed anyway regardless of the lazytime fix"
