| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace all uses of kmem_cache_t with struct kmem_cache. The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and ocfs2_dir_iops.

| * ocfs2: Remove struct ocfs2_journal_handle in favor of handle_tMark Fasheh2006-12-01
| | | | | | | | | | | | | | | | | | | | 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 ocfs2_commit_trans() becomes very straight forward, and we remove some out of date comments / code.

| * ocfs2: remove handle argument to ocfs2_start_trans()Mark Fasheh2006-12-01
| | | | | | | | | | | | | | | | | | 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. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| * ocfs2: remove unused handle argument from ocfs2_meta_lock_full()Mark Fasheh2006-12-01

| | | | | | | | | | | | | | | | | | | | This gets us rid of a slab we no longer need, as well as removing the majority of what's left on ocfs2_journal_handle. ocfs2_commit_unstarted_handle() has no more real work to do, so remove that function too.

| | | | | | | | | | | | | | | | We can also delete the unused infrastructure which was once in place to support this functionality. ocfs2_inode_private loses ip_handle and ip_handle_list. ocfs2_journal_handle loses handle_list. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| * ocfs2: don't use handle for locking in allocation functionsMark Fasheh2006-12-01
| | | | | | | | | | | | | | | | | | 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. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

* [PATCH] r/o bind mounts: clean up OCFS2 nlink handlingMark Fasheh2006-10-01
| | | | | | | | | | | | | | | | | | | | | | OCFS2 does some operations on i_nlink, then reverts them if some of its operations fail to complete. This does not fit in well with the drop_nlink() logic where we expect i_nlink to stay at zero once it gets there. So, delay all of the nlink operations until we're sure that the operations have completed. Also, introduce a small helper to check whether an inode has proper "unlinkable" i_nlink counts no matter whether it is a directory or regular inode. This patch is broken out from the others because it does contain some logical changes.

* [PATCH] r/o bind mounts: unlink: monitor i_nlinkDave Hansen2006-10-01
| | | | | | | | | | | | | | | | | When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.

* [PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2006-09-27
| | | | | | | | | | | | | | | | This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

* [PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_privateTheodore Ts'o2006-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.
