xfs: support lowmode allocations in xfs_bmap_exact_minlen_extent_alloc

Browse source

commit 6aac770598 upstream.

Currently the debug-only xfs_bmap_exact_minlen_extent_alloc allocation
variant fails to drop into the lowmode last resort allocator, and
thus can sometimes fail allocations for which the caller has a
transaction block reservation.

Fix this by using xfs_bmap_btalloc_low_space to do the actual allocation.
