Leon Romanovsky d83187dda9 IB/IPoIB: Convert IPoIB to memalloc_noio_* calls ... Commit 21caf2fc19 ("mm: teach mm by current context info to not do I/O during memory allocation") added the memalloc_noio_(save|restore) functions to enable people to modify the MM behavior by disabling I/O during memory allocation. This was further extended in Fixes: 934f3072c1 ("mm: clear __GFP_FS when PF_MEMALLOC_NOIO is set"). memalloc_noio_* functions prevent allocation paths recursing back into the filesystem without explicitly changing the flags for every allocation site. However the IPoIB hasn't been keeping up with the changes and missed completely these memalloc_noio_* calls. This led to update of allocation site with special QP creation flag, see commit 09b93088d7 ("IB: Add a QP creation flag to use GFP_NOIO allocations"), while this flag is supported by small number of drivers in IB stack. Let's change it by updating to memalloc_noio_* calls and allow for every driver underneath enjoy NOIO allocations.
