/*

|
* Sort buffer items for log recovery. Most buffer items should end up on the
|
|
* buffer list and are recovered first, with the following exceptions:
|
|
*
|
|
* 1. XFS_BLF_CANCEL buffers must be processed last because some log items
|
|
* might depend on the incor ecancellation record, and replaying a cancelled
|
|
* buffer item can remove the incore record.
|
|
*
|
|
* 2. XFS_BLF_INODE_BUF buffers are handled after most regular items so that
|
|
* we replay di_next_unlinked only after flushing the inode 'free' state
|
|
* to the inode buffer.
|
|
*
|
|
* See xlog_recover_reorder_trans for more details.
