Subject: [PATCH 10/18] fsverity: box up the write_merkle_tree_block parameters too
Date: Mon, 29 Apr 2024 20:22:01 -0700	[thread overview]
Message-ID: <171444679759.955480.7982738929684385945.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <171444679542.955480.18087310571597618350.stgit@frogsfrogsfrogs>

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

Box up the tree write request parameters into a structure so that we can
add more in the next few patches.
