Subject: [PATCH] namei fixes (14/19)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4b7b9772e4c3d87e649d4c419d2487aacf1235aa;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] namei fixes (14/19)

shifted conditional mntput() into do_follow_link() - all callers were doing
the same thing.

Obviously equivalent transformation.
