When compression is on, the cow_file_range code is farmed off to worker threads. This allows us to do significant CPU work in parallel on SMP machines. But it is a delicate balance around when we clear flags and how. In the past we cleared the delalloc flag immediately, which was safe because the pages stayed locked. But this is causing problems with the newest ENOSPC code, and with the recent extent state cleanups we can now clear the delalloc bit at the same time the uncompressed code does.
