Hi,
I have an SD card, a partition of which is mounted and is accessed
only through VFS, and certain sectors out of this partition having
some special data which is accessed by the applications only through
certain ioctls to the device.
My problem is in synchronizing/serializing these two accesses to the
hardware, especially since I dont want a VFS request to be handled
by the driver inbetween two specific ioctls. I understand that the
strategy routine should be atomic and that it cant wait on a lock or
sleep. Any pointers/suggestions/help?
Mine is a 2.4 kernel with a uni-processor.
Thanks in Advance,
Roopesh.
