Subject: ... and kill anon_inode_getfile_private()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=078d8e624c1837aa8ad65e58054a4a40d7ac46d2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

... and kill anon_inode_getfile_private()

it's a seriously misguided API, now fortunately without users.
