45 : * Inode fork owner changes
46 : *
47 : * If we have been told that we have to reparent the inode fork, it's because an
48 : * extent swap operation on a CRC enabled filesystem has been done and we are
49 : * replaying it. We need to walk the BMBT of the appropriate fork and change the
50 : * owners of it.
51 : *
52 : * The complexity here is that we don't have an inode context to work with, so
53 : * after we've replayed the inode we need to instantiate one. This is where the
54 : * fun begins.
55 : *
56 : * We are in the middle of log recovery, so we can't run transactions. That
57 : * means we cannot use cache coherent inode instantiation via xfs_iget(), as
58 : * that will result in the corresponding iput() running the inode through
59 : * xfs_inactive(). If we've just replayed an inode core that changes the link
60 : * count to zero (i.e. it's been unlinked), then xfs_inactive() will run
61 : * transactions (bad!).
62 : *
63 : * So, to avoid this, we instantiate an inode directly from the inode core we've
64 : * just recovered. We have the buffer still locked, and all we really need to
65 : * instantiate is the inode core and the forks being modified. We can do this
66 : * manually, then run the inode btree owner change, and then tear down the
67 : * xfs_inode without having to run any transactions at all.
68 : *
69 : * Also, because we don't have a transaction context available here but need to
70 : * gather all the buffers we modify for writeback so we pass the buffer_list
71 : * instead for the operation to use.
