From: Al Viro Date: Fri, 30 May 2014 15:39:02 +0000 (-0400) Subject: dcache.c: call ->d_prune() regardless of d_unhashed() X-Git-Tag: v3.18-rc1~76^2~42 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2926620145095ffb0350b2312ac9d0af8537796f;p=karo-tx-linux.git dcache.c: call ->d_prune() regardless of d_unhashed() the only in-tree instance checks d_unhashed() anyway, out-of-tree code can preserve the current behaviour by adding such check if they want it and we get an ability to use it in cases where we *want* to be notified of killing being inevitable before ->d_lock is dropped, whether it's unhashed or not. In particular, autofs would benefit from that.
