  "message": "mm, slab: add static key for should_failslab()\n\nSince commit 4f6923fbb352 (\"mm: make should_failslab always available for\nfault injection\") should_failslab() is unconditionally a noinline\nfunction. This adds visible overhead to the slab allocation hotpath,\neven if the function is empty. With CONFIG_FAILSLAB\u003dy there\u0027s additional\noverhead when the functionality is not enabled by a boot parameter or\ndebugfs.\n\nThe overhead can be eliminated with a static key around the callsite.\nFault injection and error injection frameworks can now be told that the\nthis function has a static key associated, and are able to enable and\ndisable it accordingly.\n\nSigned-off-by: Vlastimil Babka \u003cvbabka@suse.cz\u003e\n",
