Subject: [PATCH 0/4] Remove un-needed 'major' registration when alloc_disk(0) is used.
Date: Thu, 10 Mar 2016 08:59:28 +1100 [thread overview]
Message-ID: <20160309215702.20904.61407.stgit@noble> (raw)
When alloc_disk(0) is used, the ->major number is ignored and
irrelevant. Yet several drivers register a major number anyway.
This series of patches removes the pointless registrations. The pmem
driver also does this, but a patch has already been sent for that
driver.
Note that I am not in a position to test these beyond simple compile
testing.
Thanks,
NeilBrown
