Update ocfs2_should_update_atime() to understand the MNT_RELATIME flag and
to test against mtime / ctime accordingly.

Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and
ocfs2_dir_iops.
This helps us avoid some multi-node races with mode change and vfs
operations.

Add splice read/write support in ocfs2.
ocfs2_file_splice_read/write are very similar to ocfs2_file_aio_read/write.

This is mostly a search and replace as ocfs2_journal_handle is now no more
than a container for a handle_t pointer.
ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.
Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
All callers either pass in NULL directly, or a local variable that is
already set to NULL.
The internals of ocfs2_start_trans() get a nice cleanup as a result.

Instead we record our state on the allocation context structure which all
callers already know about and lifetime correctly. This means the
reservation functions don't need a handle passed in any more, and we can
also take it off the alloc context.

No reason to use our wrapper struct in this function, so take the handle_t
directly.
Also fixes a bug where we were incorrectly setting the handle to NULL in
case of a failure from journal_restart()

The loop within ocfs2_zero_extend() can execute for a long time, causing
spurious soft lockup warnings.
Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
The page zeroing code was missing the region between old i_size and new
i_size for those extends that didn't actually require a change in space
allocation.

This patch vectorizes aio_read() and aio_write() methods to prepare for
collapsing all aio & vectored operations into one interface - which is
aio_read()/aio_write().

Temporarily take the meta data lock in ocfs2_file_aio_read() to allow us to
update our inode fields.
Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
We need to take a data lock around extends to protect the pages that
ocfs2_zero_extend is going to be pulling into the page cache. Otherwise an
extend on one node might populate the page cache with data pages that have
no lock coverage.

Fix ocfs2_truncate_file() so that it forces a truncate_inode_pages() on all
interested nodes in all cases of a truncate(), not just allocation change.

This is a conversion to make the various file_operations structs in fs/
const. Basically a regexp job, with a few manual fixups
The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)

This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.
