[PATCH 17/34] xfs: support logging EFIs for realtime extents

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Teach the EFI mechanism how to free realtime extents.  We're going to
need this to enforce proper ordering of operations when we enable
realtime rmap.

Declare a new log intent item type (XFS_LI_EFI_RT) and a separate defer
ops for rt extents.  This keeps the ondisk artifacts and processing code
completely separate between the rt and non-rt cases.  Hopefully this
will make it easier to debug filesystem problems.
