For bisectability, a temporary _gfp() variant of such functions were added. All call sites then got converted use the _gfp() variants and explicitly pass GFP context. Having no callers left, the original libsas notifiers were then modified to accept gfp_t flags by default. Switch back to the original event notifiers API, while still passing GFP context. The _gfp() notifier variants will be removed afterwards. Signed-off-by: Ahmed S.
