From 015af1af44003fff797f8632e940824c07d282bf Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Wed, 20 Dec 2023 17:05:26 +0100 Subject: gfs2: Mark withdraws as unlikely Mark the gfs2_withdrawn(), gfs2_withdrawing(), and gfs2_withdraw_in_prog() inline functions as likely to return %false. This allows to get rid of likely() and unlikely() annotations at the call sites of those functions.
