[PATCH 1/4] xfs: create a static name for the dot entry too

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

 



From: Darrick J. Wong <djwong@xxxxxxxxxx>

Create an xfs_name_dot object so that upcoming scrub code can compare
against that.  Offline repair already has such an object, so we're
really just hoisting it to the kernel.
