Each log item's ->finish_item function sets up a small amount of state

Each log intent item's ->finish_item call chain inevitably includes some
code to set the dirty flag of the transaction.  If there's an associated
log intent done item, it also sets the item's dirty flag and the
transaction's INTENT_DONE flag.  This is repeated throughout the
codebase.

Reduce the LOC by moving all that to xfs_defer_finish_one.

XFS_TRANS_HAS_INTENT_DONE is a flag to the CIL that we've added a log
intent done item to the transaction.  This enables an optimization
wherein we avoid writing out log intent and log intent done items if
they would have ended up in the same checkpoint.  This reduces writes to
the ondisk log and speeds up recovery as a result.

However, callers can use the defer ops machinery to modify xattrs
without using the log items.  In this situation, there won't be an
intent done item, so we do not need to set the flag.

Recreate work items for each xfs_defer_pending object when we are

Reviewed-by: Christoph Hellwig <hch@lst.de>

Now that we pass the xfs_defer_pending object into the intent item
recovery functions, we know exactly when ownership of the sole refcount
passes from the recovery context to the intent done item.  At that
point, we need to null out dfp_intent so that the recovery mechanism
won't release it.  This should fix the UAF problem reported by Long Li.

Note that we still want to recreate the full deferred work state.  That
will be addressed in the next patches.

Now that log intent item recovery recreates the xfs_defer_pending state,

Signed-off-by: Darrick J. Wong <djwong@kernel.org>
Reviewed-by: Christoph Hellwig <hch@lst.de>

One thing I never quite got around to doing is porting the log intent
item recovery code to reconstruct the deferred pending work state.  As a
result, each intent item open codes xfs_defer_finish_one in its recovery
method, because that's what the EFI code did before xfs_defer.c even
existed.

This is a gross thing to have left unfixed -- if an EFI cannot proceed
due to busy extents, we end up creating separate new EFIs for each
unfinished work item, which is a change in behavior from what runtime
would have done.

Worse yet, Long Li pointed out that there's a UAF in the recovery code.
The ->commit_pass2 function adds the intent item to the AIL and drops
the refcount.  The one remaining refcount is now owned by the recovery
mechanism (aka the log intent items in the AIL) with the intent of
giving the refcount to the intent done item in the ->iop_recover
function.

However, if something fails later in recovery, xlog_recover_finish will
walk the recovered intent items in the AIL and release them.  If the CIL
hasn't been pushed before that point (which is possible since we don't
force the log until later) then the intent done release will try to free
its associated intent, which has already been freed.

This patch starts to address this mess by having the ->commit_pass2
functions recreate the xfs_defer_pending state.  The next few patches
will fix the recovery functions.

If recovery finds an xattr log intent item calling for the removal of an
attribute and the file doesn't even have an attr fork, we know that the
removal is trivially complete.  However, we can't just exit the recovery
function without doing something about the recovered log intent item --
it's still on the AIL, and not logging an attrd item means it stays
there forever.

This has likely not been seen in practice because few people use LARP
and the runtime code won't log the attri for a no-attrfork removexattr
operation.  But let's fix this anyway.

Also we shouldn't really be testing the attr fork presence until we've
taken the ILOCK, though this doesn't matter much in recovery, which is
single threaded.

This way is fine from driver viewpoint, because flush sequence is block
layer concept, and it isn't related with driver.

However, driver(such as dm-rq) can call blk_mq_queue_inflight() to count &
drain inflight requests, then the wait & drain never gets done because
the completed & not-finished flush request is counted as inflight.

Fix this issue by not counting completed flush data request as inflight in
case of quiesce.

The variable phys is defined as (struct resource *) which aligns with
the printk format specifier %pr. Taking the address of it results in a
value of type (struct resource **) which is incompatible with the format
specifier %pr. Therefore, remove the address of operator (&).

Since the rethook::handler is an RCU-maganged pointer so that it will
notice readers the rethook is stopped (unregistered) or not, it should
be an __rcu pointer and use appropriate functions to be accessed. This
will use appropriate memory barrier when accessing it. OTOH,
rethook::data is never changed, so we don't need to check it in
get_kretprobe().

NOTE: To avoid sparse warning, rethook::handler is defined by a raw
function pointer type with __rcu instead of rethook_handler_t.
