Jan Kara bf097aaff4 quota: Make quota code not call tty layer with dqptr_sem held ... dqptr_sem can be called from slab reclaim. tty layer uses GFP_KERNEL mask for allocation so it can end up calling slab reclaim. Given quota code can call into tty layer to print warning this creates possibility for lock inversion between tty->atomic_write_lock and dqptr_sem. Using direct printing of warnings from quota layer is obsolete but since it's easy enough to change quota code to not hold any locks when printing warnings, let's just do it. It seems like a good thing to do even when we use netlink layer to transmit warnings to userspace.
