[PATCH] nfs: make nfs_initialise_sb() static and deinline it

From: Denys Vlasenko
Date: Fri Apr 15 2016 - 12:02:30 EST


nfs_initialise_sb() is only used in fs/nfs/super.c, no need to be global.

superblock init is not a performance-critical operation, no need to inline.
It compiles to 220 bytes and has two callsites.
