patches are basically in three categories: (1) patches related to
broken xfstest cases, (2) patches related to improving iomap and
start using it in GFS2, and (3) general typos and clarifications.
Please note that one of the iomap patches extends beyond GFS2 and
affects other file systems, but it was publically reviewed by a
variety of file system people in the community.
1. Andreas has a patch that simply renames variable 'bsize' to 'factor'
to clarify the logic related to gfs2_block_map.
2. He also has a patch to correctly set ctime in the setflags ioctl,
which fixes broken xfstests test 277.
3. He also fixed broken xfstest 258, due to an atime initialization
problem.
4. He also fixed broken xfstest 307, in which GFS2 was not setting
ctime when setting acls.
5. He has a patch to switch general iomap code from blkno to disk
offset for a variety of file systems.
6. He has a patch to add a new IOMAP_F_DATA_INLINE flag for iomap
to indicate blocks that have data mixed with metadata.
7. I contributed a patch to make inode height info part of the
'metapath' data structure to facilitate using iomap in GFS2.
8. I have a patch to start using iomap inside GFS2 and switch GFS2's
block_map functions to use iomap under the covers.
9. I have a patch to switch GFS2's fiemap implementation from using
block_map to using iomap under the covers.
10. Andreas has a patch to implement SEEK_HOLE and SEEK_DATA via
iomap in GFS2.
11. I have a patch related to journaled data pages not being properly
synced to media when writing inodes. This was caught with xfstests.
12. I have a patch to fix another failing xfstest case in which
switching a file from ordered_write to journaled data via set_flags
caused a deadlock.
13. Andreas has a patch to fix failing xfstest case 066, which was
due to not properly syncing dirty inodes when changing extended
attributes.
14. Andreas fixed a minor typo in a comment.
15. Andreas contributed a patch to partially fix xfstest 424, which
involved GET_FLAGS and SET_FLAGS ioctl. This is also a cleanup
and simplification of the translation of flags from fs flags to
gfs2 flags.
16. He also added support for STATX_ATTR_ in statx, which fixed broken
xfstest 424.
17. He also contributed a fix for failing xfstest 093 which fixes a
recursive glock problem with gfs2_xattr_get and _set.

Pull btrfs updates from David Sterba:
"There are some new user features and the usual load of invisible
enhancements or cleanups.
New features:
- extend mount options to specify zlib compression level, -o
compress=zlib:9
- v2 of ioctl "extent to inode mapping", addressing a usecase where
we want to retrieve more but inaccurate results and do the
postprocessing in userspace, aiding defragmentation or
deduplication tools
- populate compression heuristics logic, do data sampling and try to
guess compressibility by: looking for repeated patterns, counting
unique byte values and distribution, calculating Shannon entropy;
this will need more benchmarking and possibly fine tuning, but the
base should be good enough
- enable indexing for btrfs as lower filesystem in overlayfs
- speedup page cache readahead during send on large files
Internal enhancements:
- more sanity checks of b-tree items when reading them from disk
- more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other
errno or error handling fixes
- remove some homegrown IO-related logic, that's been obsoleted by
core block layer changes (batching, plug/unplug, own counters)
- add ref-verify, optional debugging feature to verify extent
reference accounting
- simplify code handling outstanding extents, make it more clear
where and how the accounting is done
- make delalloc reservations per-inode, simplify the code and make
the logic more straightforward
- extensive cleanup of delayed refs code
Notable fixes:
- fix send ioctl on 32bit with 64bit kernel"

will be able to iterate every piece of metadata in the filesystem to
look for obvious errors and corruptions. In the next release cycle

metadata, so this feature should only be used by the developers in the

Pull xfs updates from Darrick Wong:
"xfs: great scads of new stuff for 4.15.
This merge cycle, we're making some substantive changes to XFS. The
in-core extent mappings have been refactored to use proper iterators
and a btree to handle heavily fragmented files without needing
high-order memory allocations; some important log recovery bug fixes;
and the first part of the online fsck functionality.
(The online fsck feature is disabled by default and more pieces of it
will be coming in future release cycles.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported.
New in this version:
- Refactor the incore extent map manipulations to use a cursor
instead of directly modifying extent data.
- Refactor the incore extent map cursor to use an in-memory btree
instead of a single high-order allocation. This eliminates a major
source of complaints about insufficient memory when opening a
heavily fragmented file into a system whose memory is also heavily
fragmented.
- Fix a longstanding bug where deleting a file with a complex
extended attribute btree incorrectly handled memory pointers, which

Currently we rely on the first byte of the Rx buffer to check if there's
any data available to be read. If the first byte of the received buffer
is zero (i.e. null character), then we fail to signal that data is
available even when it's available.
Instead introduce a boolean variable to track the data availability and
update it in the channel receive callback as ready and clear it when the
data is read.

Currently the mailbox framework sets txdone_method to TXDONE_BY_POLL if
the controller sets txdone_by_poll. However some clients can have a
mechanism to do TXDONE_BY_ACK which they can specify by knows_txdone.
However, we endup setting both TXDONE_BY_POLL and TXDONE_BY_ACK in that
case. In such scenario, we may end up with below warnings as the tx
ticker is run both by mailbox framework and the client.

Previously we programmed the LTR_L1.2_THRESHOLD in the parent (upstream)
device using the capability pointer of the *child* (downstream) device,
which corrupted some random word of the parent's config space.
Use the parent's L1 SS capability pointer to program its
LTR_L1.2_THRESHOLD.

The LPI transitioning logic in stmmac_main uses
priv->tx_path_in_lpi_mode to enter/exit LPI.
However, priv->tx_path_in_lpi_mode is assigned
using the return value from host_irq_status().
So for dwmac4, priv->tx_path_in_lpi_mode was always false,
so stmmac_tx_clean() would always try to put us in eee mode,
and stmmac_xmit() would never take us out of eee mode.
To fix this, make host_irq_status() read and return the LPI
irq status also for dwmac4.
This also increments the existing LPI counters, so that
ethtool --statistics shows LPI transitions also for dwmac4.
For dwmac1000, irqs are enabled/disabled using the register
named "Interrupt Mask Register", and thus setting a bit disables
that specific irq.
For dwmac4 the matching register is named "MAC_Interrupt_Enable",
and thus setting a bit enables that specific irq.
Looking at dwmac1000_core.c, the irqs that are always enabled are:
LPI and PMT.
Looking at dwmac4_core.c, the irqs that are always enabled are:
PMT.
To be able to read the LPI irq status, we need to enable the LPI
irq also for dwmac4.
