fs: super: use GFP_KERNEL instead of GFP_USER for super block allocation

Browse source

There is no reason to use a GFP_USER flag for struct super_block allocation
in the alloc_super(). Instead, let's use GFP_KERNEL for that.

>From the memory management perspective, the only difference between
GFP_USER and GFP_KERNEL is that GFP_USER allocations are tied to a cpuset,
while GFP_KERNEL ones are not.

There is no real issue and this is not a candidate to go to the stable,
but let's fix it for a consistency sake.
