Subject: [PATCH 03/29] xfs: create a helper to compute the blockcount of a max sized remote value
Date: Fri, 29 Mar 2024 17:36:50 -0700 [thread overview]
Message-ID: <171175868610.1988170.11402681235329108487.stgit@frogsfrogsfrogs> (raw)

From: Darrick J. Wong <djwong@kernel.org>
Create a helper function to compute the number of fsblocks needed to
store a maximally-sized extended attribute value.
