Subject: autofs4: kill ->size in autofs_info
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0bf71d4d005176f6b6587ba64a377f9798213f21;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

autofs4: kill ->size in autofs_info

It's used only to pass the length of symlink body to
autofs4_get_inode() in autofs4_dir_symlink().  We can
bloody well set inode->i_size in autofs4_dir_symlink()
directly and be done with that.
