* [PATCH 2/2] ocfs2: Implement group add for online resizeTao Ma2008-01-251-0/+3
| | | | | | | | | | | | | | | | This patch adds the ability for a userspace program to request that a properly formatted cluster group be added to the main allocation bitmap for an Ocfs2 file system. The request is made via an ioctl, OCFS2_IOC_GROUP_ADD. On a high level, this is similar to ext3, but we use a different ioctl as the structure which has to be passed through is different. During an online resize, tunefs.ocfs2 will format any new cluster groups which must be added to complete the resize, and call OCFS2_IOC_GROUP_ADD on each one. Kernel verifies that the core cluster group information is valid and then does the work of linking it into the global allocation bitmap.

* [PATCH 1/2] ocfs2: Add group extend for online resizeTao Ma2008-01-251-0/+3
| | | | | | | | | | | | | This patch adds the ability for a userspace program to request an extend of last cluster group on an Ocfs2 file system. The request is made via ioctl, OCFS2_IOC_GROUP_EXTEND. This is derived from EXT3_IOC_GROUP_EXTEND, but is obviously Ocfs2 specific. tunefs.ocfs2 would call this for an online-resize operation if the last cluster group isn't full.

* ocfs2: Write support for inline dataMark Fasheh2007-10-121-0/+3
| | | | | | | | | | | | | | | | | | This fixes up write, truncate, mmap, and RESVSP/UNRESVP to understand inline inode data. For the most part, the changes to the core write code can be relied on to do the heavy lifting. Any code calling ocfs2_write_begin (including shared writeable mmap) can count on it doing the right thing with respect to growing inline data to an extent tree. Size reducing truncates, including UNRESVP can simply zero that portion of the inode block being removed. Size increasing truncatesm, including RESVP have to be a little bit smarter and grow the inode to an extent tree if necessary.

* ocfs2: support for removing file regionsMark Fasheh2007-07-101-0/+2
| | | | | | | | | | Provide an internal interface for the removal of arbitrary file regions. ocfs2_remove_inode_range() takes a byte range within a file and will remove existing extents within that range. Partial clusters will be zeroed so that any read from within the region will return zeros. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: make room for unwritten extents flagMark Fasheh2007-04-261-1/+1
| | | | | | | | | | Due to the size of our group bitmaps, we'll never have a leaf node extent record with more than 16 bits worth of clusters. Split e_clusters up so that leaf nodes can get a flags field where we can mark unwritten extents. Interior nodes whose length references all the child nodes beneath it can't split their e_clusters field, so we use a union to preserve sizing there.

* ocfs2: ocfs2_link() journal credits updateMark Fasheh2007-02-011-2/+2
| | | | | | | | | | Commit 592282cf2eaa33409c6511ddd3f3ecaa57daeaaa fixed some missing directory c/mtime updates in part by introducing a dinode update in ocfs2_add_entry(). Unfortunately, ocfs2_link() (which didn't update the directory inode before) is now missing a single journal credit. Fix this by doubling the number of inode updates expected during hard link creation. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: local mountsSunil Mushran2006-12-071-1/+4
| | | | | | | | | | This allows users to format an ocfs2 file system with a special flag, OCFS2_FEATURE_INCOMPAT_LOCAL_MOUNT. When the file system sees this flag, it will not use any cluster services, nor will it require a cluster configuration, thus acting like a 'local' file system.

| * ocfs2: Remove struct ocfs2_journal_handle in favor of handle_tMark Fasheh2006-12-011-11/+10
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | 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.
