Prev: [PATCH] panic: keep blinking in spite of long spin timer mode
Next: [PATCHv2 0/3] [RFC] AIO: Fix reference counting in aio_cancel_all() and io_cancel()
From: Sergey Temerkhanov on 27 May 2010 18:50
The attached files are respectively:
- a kernel module which implements 4 pseudo-devices with different
aio_read/aio_write methods:
- aiotest0 simply returns -EIOCBQUEUED;
- aiotest1 sets ki_cancel method and returns -EIOCBQUEUED;
- aiotest2 sets KIF_CANCELLED flag and returns -EINTR;
- aiotest3 sets ki_cancel method and returns -EIOCBQUEUED after 1 second;

- a program test_aio.c which submits 1 AIO request and calls
io_destroy() after 1 second timeout
- a program test_aio.c which submits 1 AIO request and calls
io_cancel() on that request immediately.
