Subject: [PATCH 4/9] fuse2fs: consolidate file handle checking in op_ioctl
Date: Thu, 06 Nov 2025 14:37:11 -0800	[thread overview]
Message-ID: <176246794236.2862990.7332845914069269587.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <176246794125.2862990.7275258954976277948.stgit@frogsfrogsfrogs>

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

Reduce code size by checking the file handle in op_ioctl dispatch
instead of every single ioctl implementation.
