For example, the uswsusp interface invokes it in\nSNAPSHOT_CREATE_IMAGE, SNAPSHOT_UNFREEZE, and snapshot_release().\nBefore the stacking change this was a silent no-op; it now triggers\na spurious WARNING.\n\nRemove the WARN_ON() wrapper from the !saved_gfp_count check while\nretaining the check itself, so that defensive calls remain harmless\nwithout producing false warnings.\n\n[ rjw: Subject tweak ]"
