xfs_repair was not detecting that version 3 inodes are invalid for
for non-CRC filesystems. The result is specific inode corruptions go
undetected and hence aren't repaired if only the version number is
out of range.
The core of the problem is that the XFS_DINODE_GOOD_VERSION() macro
doesn't know that valid inode versions are dependent on a superblock
version number. Fix this in libxfs, and propagate the new function
out into the rest of xfsprogs to fix the issue.

As part of the inode block map intent log item recovery process, we
had to set the IRECOVERY flag to prevent an unlinked inode from
being truncated during the first iput call. This required us to set
MS_ACTIVE so that iput puts the inode on the lru instead of
immediately evicting the inode.
Unfortunately, if the mount fails later on, the inodes that have
been loaded (root dir and realtime) actually need to be evicted
since we're aborting the mount. If we don't clear MS_ACTIVE in the
failure step, those inodes are not evicted and therefore leak. The
leak was found by running xfs/130 and rmmoding xfs immediately after
the test.

XFS historically took the iolock exclusive when invalidating pages
before direct I/O operations to protect against writeback starvations.
But this writeback starvation issues has been fixed a long time ago
in the core writeback code, and all other file systems manage to do
without the exclusive lock. Convert XFS over to avoid the exclusive
lock in this case, and also move to range invalidations like done
by the other file systems.

Reverting this patch, as it incorrectly assumes the additional length
for INQUIRY in target_complete_cmd_with_length() is SCSI allocation
length, which breaks existing user-space code when SCSI allocation
length is smaller than additional length.

inquiry: got too few bytes (0)
INQUIRY resid (32) should never exceed requested len=4
inquiry: failed requesting 4 byte response: Malformed response to

so go ahead and revert to original logic for now.

As described in section 6.3.3 of spc4r22:

copy manager is unable to establish communications with a copy target
device, because the copy target device does not respond to INQUIRY,

If UBIFS is facing an error while walking a directory, it reports this
error and ubifs_readdir() returns the error code. But the VFS readdir
logic does not make the getdents system call fail in all cases. When the
readdir cursor indicates that more entries are present, the system call
will just return and the libc wrapper will try again since it also
knows that more entries are present.
This causes the libc wrapper to busy loop for ever when a directory is
corrupted on UBIFS.
A common approach do deal with corrupted directory entries is
skipping them by setting the cursor to the next entry. On UBIFS this
approach is not possible since we cannot compute the next directory
entry cursor position without reading the current entry. So all we can
do is setting the cursor to the "no more entries" position and make
getdents exit.
