#     
#     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"
