Linus Torvalds e6e6ec48dd fscrypt fix for v5.6-rc6
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.
