Subject: One less parameter to __d_path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=329c97f0af41bd580237b8fad0f3741849ee4e13;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

One less parameter to __d_path

All callers to __d_path pass the dentry and vfsmount of a struct path to
__d_path.  Pass the struct path directly, instead.
