Subject: Smack: pipefs fix in smack_d_instantiate
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8da4aba5bf9869f58d2a6bb30daaf54b2fa72569;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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.
