Subject: [PATCH 07/28] vfs: rename vfs_clone_file_prep to be more descriptive
Date: Sun, 21 Oct 2018 09:15:51 -0700	[thread overview]
Message-ID: <154013855179.29026.12300431992865619414.stgit@magnolia> (raw)
In-Reply-To: <154013850285.29026.16168387526580596209.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

The vfs_clone_file_prep is a generic function to be called by filesystem
implementations only.  Rename the prefix to generic_ and make it more
clear that it applies to remap operations, not just clones.
