ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant
and switched everything to scalar nanoseconds. The union remained, but
become completely pointless.Get rid of the union and just keep ktime_t as simple typedef of type s64.
The conversion was done with coccinelle and some manual mopping up.

Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
which are bio (or rq) private, and which ones are shared. From
Christoph.- A set of patches from Bart, that improve how we handle queue
stopping and starting in blk-mq.- Support for WRITE_ZEROES from Chaitanya.
- Lightnvm updates from Javier/Matias.
- Supoort for FC for the nvme-over-fabrics code. From James Smart.
- A bunch of fixes from a whole slew of people, too many to name
here"* 'for-4.10/block' of git://git.kernel.dk/linux-block: (182 commits)

CURRENT_TIME is not y2038 safe.
Use y2038 safe ktime_get_real_seconds() here for timestamps. struct
heartbeat_block's hb_seq and deletetion time are already 64 bits wide
and accommodate times beyond y2038.Also use y2038 safe ktime_get_real_ts64() for on disk inode timestamps.
These are also wide enough to accommodate time64_t.Link: http://lkml.kernel.org/r/1475365298-29236-1-git-send-email-deepa.kernel@gmail.com

struct timespec is not y2038 safe. Use time64_t which is y2038 safe to
represent orphan scan times. time64_t is sufficient here as only the
seconds delta times are relevant.Also use appropriate time functions that return time in time64_t format.
Time functions now return monotonic time instead of real time as only
delta scan times are relevant and these values are not persistent across
reboots.The format string for the debug print is still using long as this is
only the time elapsed since the last scan and long is sufficient to
represent this value.Link: http://lkml.kernel.org/r/1475365138-20567-1-git-send-email-deepa.kernel@gmail.com

In ocfs2_lock_refcount_tree, if ocfs2_read_refcount_block() returns an
error, we do ocfs2_refcount_tree_put twice (once in
ocfs2_unlock_refcount_tree and once outside it), thereby reducing the
refcount of the refcount tree twice, but we dont delete the tree in this
case. This will make refcnt of the tree = 0 and the
ocfs2_refcount_tree_put will eventually call ocfs2_mark_lockres_freeing,
setting OCFS2_LOCK_FREEING for the refcount_tree->rf_lockres.The error returned by ocfs2_read_refcount_block is propagated all the
way back and for next iteration of write, ocfs2_lock_refcount_tree gets
the same tree back from ocfs2_get_refcount_tree because we havent

Connect the new VFS clone_range, copy_range, and dedupe_range features
to the existing reflink capability of ocfs2. Compared to the existing
ocfs2 reflink ioctl We have to do things a little differently to support
the VFS semantics (we can clone subranges of a file but we don't clone
xattrs), but the VFS ioctls are more broadly supported.Signed-off-by: Darrick J. Wong
---
v2: Convert inline data files to extents files before reflinking,
and fix i_blocks so that stat(2) output is correct.
v3: Make zero-length dedupe consistent with btrfs behavior.
v4: Use VFS double-inode lock routines and remove MAX_DEDUPE_LEN. -
When ocfs2 shares blocks from one file to another, it's necessary to
charge that many blocks to the quota because ocfs2 tallies block charges
according to the number of blocks mapped, not the number of physical
blocks used.Without this patch, reflinking X blocks and then CoWing all of them
causes quota usage to *decrease* by X as seen in generic/305.Signed-off-by: Darrick J. Wong

when we need an extent split but not a refcount split because meta_ac

The following panic was caught when run ocfs2 disconfig single test

-ENOSPC, that means credits were used up.The total credit should include 3 times of "num_dx_leaves" from
ocfs2_dx_dir_rebalance(), because 2 times will be consumed in
ocfs2_dx_dir_transfer_leaf() and 1 time will be consumed in
ocfs2_dx_dir_new_cluster() -> __ocfs2_dx_dir_new_cluster() ->
ocfs2_dx_dir_format_cluster(). But only two times is included in
ocfs2_dx_dir_rebalance_credits(), fix it.This can cause read-only fs(v4.1+) or panic for mainline linux depending
on mount option.------------[ cut here ]------------

The extern struct variable ocfs2_inode_cache is not defined. It meant to
use ocfs2_inode_cachep defined in super.c, I think. Fortunately it is
not used anywhere now, so no impact actually. Clean it up to fix this
mistake.Link: http://lkml.kernel.org/r/57E1E49D.8050503@huawei.com
