Subject: BACKPORT: Smack: pipefs fix in smack_d_instantiate
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9fe6af6b6e2c7bd8c7fe3e1ab46a0ac839cd9e7c;p=platform%2Fkernel%2Flinux-stable.git

BACKPORT: Smack: pipefs fix in smack_d_instantiate

This fix writes the task label when
smack_d_instantiate is called, before the
label of the superblock was written on the
pipe's inode.
