Subject: [PATCH 0/2] kernfs: remove i_lock usage that isn't needed
Date: Tue, 18 Oct 2022 10:32:34 +0800 [thread overview]
Message-ID: <166606025456.13363.3829702374064563472.stgit@donald.themaw.net> (raw)
In the patch series to change the global kernfs mutex to a read-write
semaphore the inode i_lock is used in several functions.
But after thinking about it the i_lock is in fact not needed.
Signed-off-by: Ian Kent <raven@themaw.net>
