| |
I am seeing an oops and message indicating that the VFS buffer free lists are getting corrupted under 2.2.15 when I use NWFS with multiple SMP threads with the Linux Buffer Cache. The NWFS LRU works just fine, however.
If I put a big lock over all accesses and make all the interactions with the buffer cache synchronous, the problem goes away.
Is it required that I hold the kernel lock with lock_kernel() over the Linux Buffer Cache when doing I/O to it in 2.2.15?
Jeff
