We have three remaining callers of xfs_trans_dup:
- xfs_itruncate_extents which open codes xfs_trans_roll
- xfs_bmap_finish doesn't have an xfs_inode argument and thus leaves
attaching them to it's callers, but otherwise is identical to
xfs_trans_roll
- xfs_dir_ialloc looks at the log reservations in the old xfs_trans
structure instead of the log reservation parameters, but otherwise
is identical to xfs_trans_roll.
By allowing a NULL xfs_inode argument to xfs_trans_roll we can switch
these three remaining users over to xfs_trans_roll and mark xfs_trans_dup
static.

The flags value always was 0 or XFS_TRANS_ABORT. Switch to a bool
parameter to allow further cleanups.

To: xfs
xfs_trans_cancel takes two flags arguments: XFS_TRANS_RELEASE_LOG_RES and
XFS_TRANS_ABORT. Both of them are a direct product of the transaction
state, and can be deducted:
- any dirty transaction needs XFS_TRANS_ABORT to be properly canceled,
and XFS_TRANS_ABORT is a noop for a transaction that is not dirty.
- any transaction with a permanent log reservation needs
XFS_TRANS_RELEASE_LOG_RES to be properly canceled, and passing
XFS_TRANS_RELEASE_LOG_RES for a transaction without a permanent
log reservation is invalid.
So just remove the flags argument and do the right thing.

5 siblings, 0 replies; 7+ messages in thread
From: Christoph Hellwig @ 2015-06-03 12:49 UTC (permalink / raw)
To: xfs
The flags argument to xfs_trans_commit is not useful for most callers, as
a commit of a transaction without a permanent log reservation must pass
0 here, and all callers for a transaction with a permanent log reservation
except for xfs_trans_roll must pass XFS_TRANS_RELEASE_LOG_RES. So remove
the flags argument from the public xfs_trans_commit interfaces, and
introduce low-level __xfs_trans_commit variant just for xfs_trans_roll
that regrants a log reservation instead of releasing it.

5 siblings, 0 replies; 7+ messages in thread
From: Christoph Hellwig @ 2015-06-03 12:49 UTC (permalink / raw)
To: xfs
Instead of the confusing flags argument pass a boolean flag to indicate if
we want to release or regrant a log reservation.
Also ensure that xfs_log_done always drop the reference on the log ticket,
to both simplify the code and make the logic in xfs_trans_roll easier
to understand.

Hi Christoph, with this series now committed to the kernel code, can
you port it to the xfsprogs codebase? The for-next branch of the
git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git tree woul dbe
the best target as it should mostly just apply to the libxfs/ side
of things. Thanks!
Cheers,
Dave.
