Subject: 9p: statfs should not override server f_type
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5bdad93387c64f0095df7ae9a252ff44234a8b3f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

9p: statfs should not override server f_type

Allow a 9p2000.L server to supply the statfs f_type value rather than
hardwiring V9FS_MAGIC.  It is desirable to give the server this option
in some applications, e.g. I/O forwarding.
