The "%Ld" specifier, which represents long long unsigned, doesn't meet C language standard, and even more, it makes people easily mistake with "%ld", which represent long unsigned. So replace "%Ld" with "lld". Do the same with "%Lu". Signed-off-by: Zeng Heng <zengheng4@huawei.com> Reviewed-by: Darrick J.

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