Subject: [PATCH 2/2] xfs: rename struct xfs_eofblocks to xfs_icwalk
Date: Sun, 06 Jun 2021 10:54:35 -0700	[thread overview]
Message-ID: <162300207545.1202657.10696106148369657206.stgit@locust> (raw)
In-Reply-To: <162300206433.1202657.5753685964265403056.stgit@locust>

From: Darrick J. Wong <djwong@kernel.org>

The xfs_eofblocks structure is no longer well-named -- nowadays it
provides optional filtering criteria to any walk of the incore inode
cache.  Only one of the cache walk goals has anything to do with
clearing of speculative post-EOF preallocations, so change the name to
be more appropriate.
