Create separate lockdep lock classes for system file's i_mutexes. They are used to guard allocations and similar things and thus rank differently than i_mutex of a regular file or directory. Signed-off-by: NJan Kara <jack@suse.cz> Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

Call this the "inode_lock" now, since it covers both data and meta data. This patch makes no functional changes. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

The meta lock now covers both meta data and data, so this just removes the now-redundant data lock. Combining locks saves us a round of lock mastery per inode and one less lock to ping between nodes during read/write. We don't lose much - since meta locks were always held before a data lock (and at the same level) ordered writeout mode (the default) ensured that flushing for the meta data lock also pushed out data anyways.

Add the disk, network and memory structures needed to support data in inode. Struct ocfs2_inline_data is defined and embedded in ocfs2_dinode for storing inline data. A new inode field, i_dyn_features, is added to facilitate tracking of dynamic inode state. Since it will be used often, we want to mirror it on ocfs2_inode_info, and transfer it via the meta data lvb.

Propagate flags such as S_APPEND, S_IMMUTABLE, etc. from i_flags into ocfs2-specific ip_attr. Hence, when someone sets these flags via a different interface than ioctl, they are stored correctly. Signed-off-by: NJan Kara <jack@suse.cz> Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

The extent map code was ripped out earlier because of an inability to deal with holes. This patch adds back a simpler caching scheme requiring far less code. Our old extent map caching was designed back when meta data block caching in Ocfs2 didn't work very well, resulting in many disk reads. These days our metadata caching is much better, resulting in no un-necessary disk reads. As a result, extent caching doesn't have to be as fancy, nor does it have to cache as many extents. Keeping the last 3 extents seen should be sufficient to give us a small performance boost on some streaming workloads. 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>

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>

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.

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. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com>

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

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>
