Subject: Doubt Regarding Multithreading and Device Driver
Date: Wed, 27 Apr 2005 20:35:28 +0530 [thread overview]
Message-ID: <699a19ea050427080545fb1676@mail.gmail.com> (raw)
hello,
I have a doubt regarding user space threads and device drivers
implementation issue.
I have a device driver for /dev/skn
It implements basic driver operations skn_open,skn_release, skn_ioctl.
I am storing something into struct file*filp->private_data.
As this is not shared across processes I am not doing any locking
stuff while accessing or putting anything into it.
Will There be a race condition in a multithreaded program in the ioctl
call on smp kernel accessing filp->private_data.
