From: Gregor Beck Date: Fri, 3 Sep 2021 14:19:11 +0200 Subject: [PATCH 337/353] fscache: fix initialisation of cookie hash table raw spinlocks Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=74b35db93d939040d86cb5aeab29939fb54e441f The original patch, 602660600bcd ("fscache: initialize cookie hash table raw spinlocks"), subtracted 1 from the shift and so still left some spinlocks uninitialized. This fixes that.
