Merge branch 'tt/misc' into dev (2019-11-19 12:25:42 -0500)
----------------------------------------------------------------
This merge window saw the the following new featuers added to ext4:
* Direct I/O via iomap (required the iomap-for-next branch from Darrick
as a prereq).
* Support for using dioread-nolock where the block size < page size.
* Support for encryption for file systems where the block size < page size.
* Rework of journal credits handling so a revoke-heavy workload will
not cause the journal to run out of space.
* Replace bit-spinlocks with spinlocks in jbd2
Also included were some bug fixes and cleanups, mostly to clean up
corner cases from fuzzed file systems and error path handling.
