Did you check the vmalloc() call in lvm_proc_get_info()?
AFAICS, lock_kernel() is missing: vmalloc() is protected by the big kernel
lock, and in 2.3 the vfs read functions are called _without_ that lock.
the vmalloc() in lvm_do_lv_create() should be OK, it's called from an
ioctl(), and they still run with the big kernel lock.
