[Qemu-devel] [PATCH] block/iscsi: allow cluster_size of 4K and greater

2014-04-28 Thread Peter Lieven
depending on the target the opt_unmap_gran might be as low as 4K. As we know use this also as a knob to activate the allocationmap feature lower the barrier. The limit 4K (and not 512) is choosen to avoid a potentially too big allocationmap. Signed-off-by: Peter Lieven --- block/iscsi.c |2 +
