Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>
Currently the XFS logging code uses the xfs_buf structure and
associated APIs to write the log buffers to disk. This requires
various special cases in the log code and is generally not very
optimal.
Instead of using a buffer just allocate a kmem_alloc_larger region for
each log buffer, and use a bio and bio_vec array embedded in the iclog
structure to write the buffer to disk. This also allows for using
the bio split and chaining case to deal with the case of a log
buffer wrapping around the end of the log.

inode_cluster_size is supposed to represent the size (in bytes) of an
inode cluster buffer. We avoid having to handle multiple clusters per
filesystem block on filesystems with large blocks by openly rounding
this value up to 1 FSB when necessary. However, we never reset
inode_cluster_size to reflect this new rounded value, which adds to the
potential for mistakes in calculating geometries.
Fix this by setting inode_cluster_size to reflect the rounded-up size if
needed, and special-case the few places in the sparse inodes code where
we actually need the smaller value to validate on-disk metadata.

[Amir] We do not call ->remap_file_range() in case the files are not

This changes behavior of the copy_file_range(2) syscall, which will
now allow cross filesystem in-kernel copy. CIFS already supports
cross-superblock copy, between two shares to the same server. This
functionality will now be available via the copy_file_range(2) syscall.

with fixes for adfs:
- factor out filename comparison, so we can be sure that adfs_compare()
(used for namei compare) and adfs_match() (used for lookup) have the
same behaviour.
- factor out filename lowering (which is not the same as tolower() which
will lower top-bit-set characters) to ensure that we have the same
behaviour when comparing filenames as when we hash them.
- factor out the object fixups, so we are applying all fixups to
directory objects in the same way, independent of the disk format.
- factor out the object name fixup (into the previously factored out
function) to ensure that filenames are appropriately translated -
for example, adfs allows '/' in filenames, which being the Unix path
separator, need to be translated to a different character, which is
normally '.' (DOS 8.3 filenames represent the . as a / on adfs, so
this is the expected reverse translation.)
- remove filename truncation; Al asked about this and apparently the
decision is to remove it. In any case, adfs's truncation was buggy,
so this rids us of that bug by removing the truncation feature.
- we now have only one location which adds the "filetype" suffix to the
filename, so there's no point that code being out of line.
- since we translate '/' into '.', an adfs filename of "/" or "//" would
end up being translated to "." and ".." which have special meanings.
In this case, change the first character to "^" to avoid these special
directory names being abused.

Commit 73118ca8ba introduced a glock reference counting bug in
gfs2_trans_remove_revoke. Given that, replacing gl_revokes with a GLF flag is
no longer useful, so revert that commit.
