* 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.

| * ocfs2: remove handle argument to ocfs2_start_trans()Mark Fasheh2006-12-011-1/+0
| | | | | | | | | | | | | | | | | | 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 ocfs2_handle_add_lock()Mark Fasheh2006-12-011-20/+0
| | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | Callers can set h_sync directly on the handle_t, whether a transaction has been started or not can be determined via the existence of the handle_t on the struct ocfs2_journal_handle. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
