Subject: finding process blocking on a system call
Date: Thu, 6 Jan 2005 04:18:30 -0800 (PST)	[thread overview]
Message-ID: <20050106121830.44661.qmail@web60609.mail.yahoo.com> (raw)

Hello linux-experts,
   I want to find whether a process blocks in a system
call due to the unavailability of the resource that is
accessed in it. For eg, if a semaphore key is not
available to the process while executing the system
calls like read, write etc, it will wait in the
TASK_INTERRUPTIBLE state. 
   Now, I don't want the process to simply sleep,
waiting for the semaphore. I want it to be added into
the runqueue again. And also, I want to determine this
in the kernel module. How can I do this? Can anyone
help me regarding this?
 I am intercepting system calls in kernel 2.4.28.

Thanks,
selva
