The function blk_get_request() can return NULL in some cases. There are
checks on it if function is called with argumetns one of which is
GFP_ATOMIC/GFP_NOIO/etc. If system couldn't find request
blk_get_request() return NULL.

drivers/ide is obsolete and scheduled for removal. I'm not sure messing
with it is remotely useful at this point ?

Agreed, I'm not applying this stuff.
