Fueled by the LSFMM discussion on removing GFP_NOFS initiated by Willy,
I've looked into the sole GFP_NOFS allocation in zonefs. As it turned out,
it is only done for zone management commands and can be removed.
After digging into more callers of blkdev_zone_mgmt() I came to the
conclusion that the gfp_mask parameter can be removed alltogether.
So this series switches all callers of blkdev_zone_mgmt() to either use
GFP_KERNEL where possible or grab a memalloc_no{fs,io} context.
The final patch in this series is getting rid of the gfp_mask parameter.
