mainline inclusion from mainline-master commit 872a90b5b46646c6d4cdc15a265a55b1adb25b49 category: bugfix bugzilla: 175270 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
------------------------------------------------------------------------
libsas event notifiers required an extension where gfp_t flags must be explicitly passed. 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 libas API, while still passing GFP context. The libsas _gfp() variants will be removed afterwards.
