This can now be trivially supported with re-use of our existing extend code. ocfs2_allocate_unwritten_extents() takes a start offset and a byte length and iterates over the inode, adding extents (marked as unwritten) until len is reached. Existing extents are skipped over. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

Older file systems which didn't support holes did a dumb calculation of i_blocks based on i_size. This is no longer accurate, so fix things up to take actual allocation into account. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

Initially, we had wired things to return a size '1' of holes. Cook up a small amount of code to find the next extent and calculate the number of clusters between the virtual offset and the next allocated extent. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

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: NMark Fasheh <mark.fasheh@oracle.com>

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: NMark Fasheh <mark.fasheh@oracle.com>

Ocfs2 currently does cluster-wide node messaging to check the open state of an inode during delete. This patch removes that mechanism in favor of an inode cluster lock which is taken at shared read when an inode is first read and dropped in clear_inode(). This allows a deleting node to test the liveness of an inode by attempting to take an exclusive lock.

We don't want to print anything at all in ocfs2_lookup() when getting an error from ocfs2_iget() - it could be something as innocuous as a signal being detected in the dlm. ocfs2_permission() should filter on -ENOENT which ocfs2_meta_lock() can return if the inode was deleted on another node.

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

ocfs2 wasn't updating c/mtime on directories during dirent creation/deletion. Fix ocfs2_unlink(), ocfs2_rename() and __ocfs2_add_entry() by adding the proper code to update the struct inode and push the change out to disk. This helps rename/unlink on nfs exported file systems in particular as those clients compare directory time values to avoid a full re-reading a directory which hasn't changed. ocfs2_rename() loses some superfluous error handling as a result of this patch.

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 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.

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.

OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>
