2012-11-14aio: rename AIOPool to AIOCBInfoStefan Hajnoczi1-2/+2
Now that AIOPool no longer keeps a freelist, it isn't really a "pool" anymore. Rename it to AIOCBInfo and make it const since it no longer needs to be modified. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-10-31aio: add generic thread-pool facilityPaolo Bonzini1-0/+282
Add a generic thread-pool. The code is roughly based on posix-aio-compat.c, with some changes, especially the following: - use QemuSemaphore instead of QemuCond; - separate the state of the thread from the return code of the worker function. The return code is totally opaque for the thread pool; - do not busy wait when doing cancellation. A more generic threadpool (but still specific to I/O so that in the future it can use special scheduling classes or PI mutexes) can have many uses: it allows more flexibility in raw-posix.c and can more easily be extended to Win32, and it will also be used to do an msync of the persistent bitmap.
