Hmmm. Here's my latest theory:
[from ll_rw_blk.c, __make_request(): ]
/*
* Loop uses two requests, 1 for loop and 1 for the real device.
* Cut max_req in half to avoid running out and deadlocking.
*/
if ((major == LOOP_MAJOR) || (major == NBD_MAJOR))
max_req >>= 1;
This assumption presumably breaks down horribly for file-backed loop devices?
The numbers of requests that the filesystem is going to generate to deal
with one loop device request may well be >1. Does this sound plausible to
anyone or have I missed something?
