| |
-stable review patch. If anyone has any objections, please let us know.
------------------ From: David Moore <dcm@acm.org>
Adds missing call to phys_to_virt() in the lib/swiotlb.c:swiotlb_sync_sg() function. Without this change, a kernel panic will always occur whenever a SWIOTLB bounce buffer from a scatter-gather list gets synced.
