Subject: affs: stop using lock_super
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a837107439ea50116e59943556d6902c09e52772;p=linux-beck.git

affs: stop using lock_super

The VFS's 'lock_super()' and 'unlock_super()' calls are deprecated and unwanted
and just wait for a brave knight who'd kill them. This patch makes AFFS stop
using them and use the buffer-head's own lock instead.
