Chunwei Chen b4ad50ac5f Use spl_fstrans_mark instead of memalloc_noio_save ... For earlier versions of the kernel with memalloc_noio_save, it only turns off __GFP_IO but leaves __GFP_FS untouched during direct reclaim. This would cause threads to direct reclaim into ZFS and cause deadlock. Instead, we should stick to using spl_fstrans_mark. Since we would explicitly turn off both __GFP_IO and __GFP_FS before allocation, it will work on every version of the kernel. This impacts kernel versions 3.9-3.17, see upstream kernel commit torvalds/linux@934f307 for reference.
