Subject: [PATCH] vt: drop redundant might_sleep() in do_con_write()
Date: Sun, 23 Feb 2020 23:34:50 -0800 [thread overview]
Message-ID: <20200224073450.292892-1-ebiggers@kernel.org> (raw)
From: Eric Biggers <ebiggers@google.com>
The might_sleep() in do_con_write() is redundant because console_lock()
already contains might_sleep(). Remove it.
