X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd9ec84da530d3a92e99ad1f52edae44533cc27f;p=linux-beck.git

bcache: Fix a lockdep splat

bch_keybuf_del() takes a spinlock that can't be taken in interrupt context -
whoops. Fortunately, this code isn't enabled by default (you have to toggle a
sysfs thing).
