2009-09-05ocfs2: Pass struct ocfs2_caching_info to the journal functions.Joel Becker1-1/+0
The next step in divorcing metadata I/O management from struct inode is to pass struct ocfs2_caching_info to the journal functions. Thus the journal locks a metadata cache with the cache io_lock function. It also can compare ci_last_trans and ci_created_trans directly. This is a large patch because of all the places we change ocfs2_journal_access..(handle, inode, ...) to ocfs2_journal_access..(handle, INODE_CACHE(inode), ...).

2009-09-05ocfs2: move ip_last_trans to struct ocfs2_caching_infoJoel Becker1-0/+1
We have the read side of metadata caching isolated to struct ocfs2_caching_info, now we need the write side. This means the journal functions. The journal only does a couple of things with struct inode. This change moves the ip_last_trans field onto struct ocfs2_caching_info as ci_last_trans. This field tells the journal whether a pending journal flush is required. Signed-off-by: Joel Becker <joel.becker@oracle.com>
2009-09-05ocfs2: Take the inode out of the metadata read/write paths.Joel Becker1-7/+14
We are really passing the inode into the ocfs2_read/write_blocks() functions to get at the metadata cache. This commit passes the cache directly into the metadata block functions, divorcing them from the inode. Signed-off-by: Joel Becker <joel.becker@oracle.com>
2009-09-05ocfs2: Change metadata caching locks to an operations structure.Joel Becker1-2/+28
We don't really want to cart around too many new fields on the ocfs2_caching_info structure. So let's wrap all our access of the parent object in a set of operations. One pointer on caching_info, and more flexibility to boot. Signed-off-by: Joel Becker <joel.becker@oracle.com>
2009-09-05ocfs2: Make the ocfs2_caching_info structure self-contained.Joel Becker1-1/+3
We want to use the ocfs2_caching_info structure in places that are not inodes. To do that, it can no longer rely on referencing the inode directly. This patch moves the flags to ocfs2_caching_info->ci_flags, stores pointers to the parent's locks on the ocfs2_caching_info, and renames the constants and flags to reflect its independant state.

2008-10-14ocfs2: Add helper function in uptodate.c for removing xattr clustersTao Ma1-0/+3
The old uptodate only handles the issue of removing one buffer_head from ocfs2 inode's buffer cache. With xattr clusters, we may need to remove multiple buffer_head's at a time. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
2006-09-21ocfs2: implement directory read-aheadMark Fasheh1-0/+2
Uptodate.c now knows about read-ahead buffers. Use some more aggressive logic in ocfs2_readdir(). The two functions which currently use directory read-ahead are ocfs2_find_entry() and ocfs2_readdir(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
