| |
This patch handles blk_register_region() return value. Earlier blk_register_region() function doesn't handle error cases, now it is added, so the callers of this function should also handle it.
Verfied on X86 based ubuntu machine. This patch depends on [PATCH 1/8] block/genhd.c: Add error handling
