* ocfs2: Add "preferred slot" mount optionSunil Mushran2007-07-101-0/+1
| | | | | | | | | ocfs2 will attempt to assign the node the slot# provided in the mount option. Failure to assign the preferred slot is not an error. This small feature can be useful for automated testing. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: fix sparse warnings in fs/ocfs2Mark Fasheh2007-05-021-6/+6
| | | | | | | None of these are actually harmful, but the noise makes looking for real problems difficult. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: zero tail of sparse files on truncateMark Fasheh2007-04-261-0/+11
| | | | | | | | | | Since we don't zero on extend anymore, truncate needs to be fixed up to zero the part of a file between i_size and and end of it's cluster. Otherwise a subsequent extend could expose bad data. This introduced a new helper, which can be used in ocfs2_write(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: teach ocfs2_file_aio_write() about sparse filesMark Fasheh2007-04-261-0/+32
| | | | | | | | | | | | Unfortunately, ocfs2 can no longer make use of generic_file_aio_write_nlock() because allocating writes will require zeroing of pages adjacent to the I/O for cluster sizes greater than page size. Implement a custom file write here, which can order page locks for zeroing. This also has the advantage that cluster locks can easily be ordered outside of the page locks.

* ocfs2: temporarily remove extent map cachingMark Fasheh2007-04-261-5/+0
| | | | | | | | | | | The code in extent_map.c is not prepared to deal with a subtree being rotated between lookups. This can happen when filling holes in sparse files. Instead of a lengthy patch to update the code (which would likely lose the benefit of caching subtree roots), we remove most of the algorithms and implement a simple path based lookup. A less ambitious extent caching scheme will be added in a later patch. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: sparse b-tree supportMark Fasheh2007-04-261-0/+7
| | | | | | | | | | | | Introduce tree rotations into the b-tree code. This will allow ocfs2 to support sparse files. Much of the added code is designed to be generic (in the ocfs2 sense) so that it can later be re-used to implement large extended attributes. This patch only adds the rotation code and does minimal updates to callers of the extent api. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: local mountsSunil Mushran2006-12-071-0/+5
| | | | | | | | | | 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 Fasheh2006-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | 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: allocation hintsMark Fasheh2006-08-071-0/+1
| | | | | | | | | Record the most recently used allocation group on the allocation context, so that subsequent allocations can attempt to optimize for contiguousness. Local alloc especially should benefit from this as the current chain search tends to let it spew across the disk. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: limit cluster bitmap information saved at mountMark Fasheh2006-08-071-1/+0
| | | | | | | | | We were storing cluster count on the ocfs2_super structure, but never actually using it so remove that. Also, we don't want to populate the uptodate cache with the unlocked block read - it is technically safe as is, but we should change it for correctness.

* ocfs2: clean up some osb fieldsMark Fasheh2006-06-291-4/+0
| | | | | | | | Get rid of osb->uuid, osb->proc_sub_dir, and osb->osb_id. Those fields were unused, or could easily be removed. As a result, we also no longer need MAX_OSB_ID or ocfs2_globals_lock. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

| | | | | | | | | Orphan dir recovery can deadlock with another process in ocfs2_delete_inode() in some corner cases. Fix this by tracking recovery state more closely and allowing it to handle inode wipes which might deadlock. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
