2009-09-22ocfs2: Create reflinked file in orphan dir.Tao Ma1-0/+6
reflink is a very complicated process, so it can't be integrated into one transaction. 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. Signed-off-by: Tao Ma <tao.ma@oracle.com>
2007-10-12ocfs2: Move directory manipulation code into dir.cMark Fasheh1-19/+0
The code for adding, removing, deleting directory entries was splattered all over namei.c. I'd rather have this all centralized, so that it's easier to make changes for inline dir data, and eventually indexed directories. None of the code in any of the functions was changed. I only removed the static keyword from some prototypes so that they could be exported. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Reviewed-by: Joel Becker <joel.becker@oracle.com>
2007-02-12[PATCH] mark struct inode_operations const 2Arjan van de Ven1-1/+1
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.

2006-12-01ocfs2: Remove struct ocfs2_journal_handle in favor of handle_tMark Fasheh1-1/+1
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 ocfs2_commit_trans() becomes very straight forward, and we remove some out of date comments / code.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: Mark Fasheh <mark.fasheh@oracle.com>
