Today, if we hit an XFS_WANT_CORRUPTED_RETURN we don't print any
information about which filesystem hit it. Passing in the mp allows
us to print the filesystem (device) name, which is a pretty critical
piece of information.
Tested by running fsfuzzer 'til I hit some.

The bulkstat main loop progress is tracked by the "lastino"
variable, which is a full 64 bit inode. However, the loop actually
works on agno/agino pairs, and so there's a significant disconnect
between the rest of the loop and the main cursor. Convert this to
use the agino, and pass the agino into the chunk formatting function
and convert it too.
This gets rid of the inconsistency in the loop processing, and
finally makes it simple for us to skip inodes at any point in the
loop simply by incrementing the agino cursor.

The error propagation is a horror - xfs_bulkstat() returns
a rval variable which is only set if there are formatter errors. Any
sort of btree walk error or corruption will cause the bulkstat walk
to terminate but will not pass an error back to userspace. Worse
is the fact that formatter errors will also be ignored if any inodes
were correctly formatted into the user buffer.
Hence bulkstat can fail badly yet still report success to userspace.
This causes significant issues with xfsdump not dumping everything
in the filesystem yet reporting success. It's not until a restore
fails that there is any indication that the dump was bad and tha
bulkstat failed. This patch now triggers xfsdump to fail with
bulkstat errors rather than silently missing files in the dump.
This now causes bulkstat to fail when the lastino cookie does not
fall inside an existing inode chunk. The pre-3.17 code tolerated
that error by allowing the code to move to the next inode chunk
as the agino target is guaranteed to fall into the next btree
record.
With the fixes up to this point in the series, xfsdump now passes on
the troublesome filesystem image that exposes all these bugs.

The loop construct has issues:
- clustidx is completely unused, so remove it.
- the loop tries to be smart by terminating when the
"freecount" tells it that all inodes are free. Just drop
it as in most cases we have to scan all inodes in the
chunk anyway.
- move the "user buffer left" condition check to the only
point where we consume space int eh user buffer.
- move the initialisation of agino out of the loop, leaving
just a simple loop control logic using the clusteridx.
Also, double handling of the user buffer variables leads to problems
tracking the current state - use the cursor variables directly
rather than keeping local copies and then having to update the
cursor before returning.

The xfs_bulkstat_agichunk formatting cursor takes buffer values from
the main loop and passes them via the structure to the chunk
formatter, and the writes the changed values back into the main loop
local variables. Unfortunately, this complex dance is full of corner
cases that aren't handled correctly.
The biggest problem is that it is double handling the information in
both the main loop and the chunk formatting function, leading to
inconsistent updates and endless loops where progress is not made.
To fix this, push the struct xfs_bulkstat_agichunk outwards to be
the primary holder of user buffer information. this removes the
double handling in the main loop.
Also, pass the last inode processed by the chunk formatter as a
separate parameter as it purely an output variable and is not
related to the user buffer consumption cursor.
Finally, the chunk formatting code is not shared by anyone, so make
it local to xfs_itable.c.

The bulkstat code has several different ways of detecting the end of
an AG when doing a walk. They are not consistently detected, and the
code that checks for the end of AG conditions is not consistently
coded. Hence the are conditions where the walk code can get stuck in
an endless loop making no progress and not triggering any
termination conditions.
Convert all the "tmp/i" status return codes from btree operations
to a common name (stat) and apply end-of-ag detection to these
operations consistently.

xfs_bulkstat() doesn't check error return from xfs_btree_increment(). In
case of specific fs corruption that could result in xfs_bulkstat()
entering an infinite loop because we would be looping over the same
chunk over and over again. Fix the problem by checking the return value
and terminating the loop properly.

The recent refactoring of the bulkstat code left a small landmine in
the code. If a inobt read fails, then the tree walk is aborted and
returns without releasing the AGI buffer or freeing the cursor. This
can lead to a subsequent bulkstat call hanging trying to grab the
AGI buffer again.

caused a regression in xfs_inumbers, which in turn broke
xfsdump, causing incomplete dumps.
The loop in xfs_inumbers() needs to fill the user-supplied
buffers, and iterates via xfs_btree_increment, reading new
ags as needed.
But the first time through the loop, if xfs_btree_increment()
succeeds, we continue, which triggers the ++agno at the bottom
of the loop, and we skip to soon to the next ag - without
the proper setup under next_ag to read the next ag.
Fix this by removing the agno increment from the loop conditional,
and only increment agno if we have actually hit the code under
the next_ag: target.

xfs_trans.h has a dependency on xfs_log.h for a couple of

anything about the log, but this dependency means that they have to
include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header
files and clean up the includes to be in dependency order.
In doing this, remove the direct include of xfs_trans_reserve.h from
xfs_trans.h so that we remove the dependency between xfs_trans.h and
xfs_mount.h. Hence the xfs_trans.h include can be moved to the

I was running some tests on bulkstat on CRC enabled filesystems when
I noticed that all the IO being issued was 8k in size, regardless of
the fact taht we are issuing sequential 8k buffers for inodes
clusters. The IO size should be 16k for 256 byte inodes, and 32k for
512 byte inodes, but this wasn't happening.
blktrace showed that there was an explict plug and unplug happening
around each readahead IO from _xfs_buf_ioapply, and the unplug was
causing the IO to be issued immediately. Hence no opportunity was
being given to the elevator to merge adjacent readahead requests and
dispatch them as a single IO.
Add plugging around the inode chunk readahead dispatch loop in
bulkstat to ensure that we don't unplug the queue between adjacent
inode buffer readahead IOs and so we get fewer, larger IO requests
hitting the storage subsystem for bulkstat.

We also avoid needing to export verifier functions, instead we

When we read inodes via bulkstat, we generally only read them once
and then throw them away - they never get used again. If we retain
them in cache, then it simply causes the working set of inodes and
other cached items to be reclaimed just so the inode cache can grow.
Avoid this problem by marking inodes read by bulkstat not to be
cached and check this flag in .drop_inode to determine whether the
inode should be added to the VFS LRU or not. If the inode lookup
hits an already cached inode, then don't set the flag. If the inode
lookup hits an inode marked with no cache flag, remove the flag and
allow it to be cached once the current reference goes away.
Inodes marked as not cached will get cleaned up by the background
inode reclaim or via memory pressure, so they will still generate
some short term cache pressure. They will, however, be reclaimed
much sooner and in preference to cache hot inodes.
