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.
