Subject: [PATCH 02/11] block: remove invalidate_partition
Date: Tue,  6 Apr 2021 08:22:53 +0200	[thread overview]
Message-ID: <20210406062303.811835-3-hch@lst.de> (raw)
In-Reply-To: <20210406062303.811835-1-hch@lst.de>

invalidate_partition has two callers, one of which already performs
the remove_inode_hash just after the call.  Just open code the
function in the two callsites.
