From 8cb471e8f82506937fe5e2e9fb0bf90f6b1f1170 Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Tue, 10 Feb 2009 20:00:41 -0800 Subject: ocfs2: Take the inode out of the metadata read/write paths. 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.

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), ...).

In order to make the original function more suitable for reflink, we modify the following inode operations. Both are tiny. 1. ocfs2_mknod_locked only use dentry for mlog, so move it to the caller so that reflink can use it without dentry. 2. ocfs2_prepare_orphan_dir only want inode to get its ip_blkno. So use ip_blkno instead.

So if the system panic in the operation, we may leave a unfinished inode in the destication directory. So we will try to create an inode in orphan_dir first, reflink it to the src file and then move it to the destication file in the end. In that way we won't be afraid of any corruption during the reflink. This patch adds 2 functions for orphan_dir operation: 1. Create a new inode in orphand dir. 2. Move an inode to a target dir. Note: fsck.ocfs2 should work for us to remove the unfinished file in the orphan_dir.
