Subject: [PATCH 337/342] 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=324135b9a8f1539dd356c377beaf882164634c5f
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.
