+Subject: [PATCH 341/347] fscache: fix initialisation of cookie hash table raw
+ spinlocks
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+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.
