I have written a driver which supports IOCTL_CALLS. When an user application within the same process create 2 threads and sends iotcl calls parallely... My driver is failing..
But when i try to print the pid in the driver ioctl code , I get 2 different process IDs.
1. I want to know, if the driver in this scenario runs in 2 different process contexts or 2 different thread context.
Using semaphore has helped to resolve the problem but i still want to know..if linux supports threads concepts at kernel-space.
Please help.
thanks,
Ben.
