The per-metadata-type ocfs2_journal_access_*() functions hook up jbd2 commit triggers and allow us to compute metadata ecc right before the buffers are written out. This commit provides ecc for inodes, extent blocks, group descriptors, and quota blocks. It is not safe to use extened attributes and metaecc at the same time yet. The ocfs2_extent_tree and ocfs2_path abstractions in alloc.c both hide the type of block at their root. Before, it didn't matter, but now the root block must use the appropriate ocfs2_journal_access_*() function. To keep this abstract, the structures now have a pointer to the matching journal_access function and a wrapper call to call it. A few places use naked ocfs2_write_block() calls instead of adding the blocks to the journal. We make sure to calculate their checksum and ecc before the write. Since we pass around the journal_access functions. Let's typedef them in ocfs2.h. Signed-off-by: NJoel Becker <joel.becker@oracle.com> Signed-off-by: NMark Fasheh <mfasheh@suse.com>

ocfs2_bread() has become ocfs2_read_virt_blocks(), with a prototype to match ocfs2_read_blocks(). The quota code, converting from ocfs2_bread(), wraps the call to ocfs2_read_virt_blocks() in ocfs2_read_quota_block(). Unfortunately, the prototype of ocfs2_read_quota_block() matches the old prototype of ocfs2_bread(). The problem is that ocfs2_bread() returned the buffer head, and callers assumed that a NULL pointer was indicative of error. It wasn't. This is why ocfs2_bread() took an int*err argument as well. The new prototype of ocfs2_read_virt_blocks() avoids this error handling confusion. Let's change ocfs2_read_quota_block() to match.

Implement functions for recovery after a crash. Functions just read local quota file and sync info to global quota file. Signed-off-by: NJan Kara <jack@suse.cz> Signed-off-by: NMark Fasheh <mfasheh@suse.com>

This patch creates a work queue for periodic syncing of locally cached quota information to the global quota files. We constantly queue a delayed work item, to get the periodic behavior. Signed-off-by: NMark Fasheh <mfasheh@suse.com> Acked-by: NJan Kara <jack@suse.cz>

For each quota type each node has local quota file. In this file it stores changes users have made to disk usage via this node. Once in a while this information is synced to global file (and thus with other nodes) so that limits enforcement at least aproximately works. Global quota files contain all the information about usage and limits. It's mostly handled by the generic VFS code (which implements a trie of structures inside a quota file). We only have to provide functions to convert structures from on-disk format to in-memory one. We also have to provide wrappers for various quota functions starting transactions and acquiring necessary cluster locks before the actual IO is really started.
