Tiger Yang d38eb8db6a ocfs2: implement i_op->permission
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.

Mark Fasheh 1fabe1481f ocfs2: Remove struct ocfs2_journal_handle in favor of handle_t
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ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.

Mark Fasheh 65eff9ccf8 ocfs2: remove handle argument to ocfs2_start_trans()
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.

Mark Fasheh da5cbf2f9d ocfs2: don't use handle for locking in allocation functions
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.

Mark Fasheh 1fc581467e ocfs2: have ocfs2_extend_trans() take handle_t
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()

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.

Arjan van de Ven 4b6f5d20b0 [PATCH] Make most file operations structs in fs/ const
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)
