ia64/err-inject: Use get_user_pages_fast() At the point of sysfs callback, the call to gup is done without mmap_sem (or any lock for that matter). This is racy. As such, use the get_user_pages_fast() alternative and safely avoid taking the lock, if possible. Signed-off-by: Davidlohr Bueso <dbueso@suse.de> Signed-off-by: Tony Luck <tony.luck@intel.com>
