[uml-devel] [PATCH] UML - limit requests on COW devices to 32 sectors
COWed devices can't handle more than 32 (64 on x86_64) sectors in one
request due to the size of the bitmap being carried around in the
io_thread_req.
Enforce that by telling the block layer not to put too many sectors in
requests to COWed devices.
