Testing carried out:
I have run KVM autotest suite with this patch
paio_cancel and use mutex
to wait for request to complete.
* Address the issue of dead code due to
MAX_GLOBAL_THREADS = MIN_GLOBAL_THREADS
The following series implements...
---
Aneesh Kumar K.V (1):
Make paio subsystem use threadlets infrastructure
Arun R Bharadwaj (1):
Move threadlets
The reason for creating this generic infrastructure is so that other subsystems,
such as virtio-9p could make use of it for offloading tasks that could block.

Hi,
This is the v8 of the patch-series to have a generic asynchronous task

This patch makes the paio subsystem use the threadlet framework thereby
decoupling asynchronous threading framework portion out of
posix-aio-compat.c
The patch has been tested with fstress.
