We still use the BKL as long as fs/lockd\nuses it and ceph might sleep, but we can flip the definition\nto a private spinlock as soon as that\u0027s done.\nAll users outside of fs/lockd get converted to use\nlock_flocks() instead of lock_kernel() where appropriate.\n\nBased on an earlier patch to use a spinlock from Matthew\nWilcox, who has attempted this a few times before, the\nearliest patch from over 10 years ago turned it into\na semaphore, which ended up being slower than the BKL\nand was subsequently reverted.\n\nSomeone should do some serious performance testing when\nthis becomes a spinlock, since this has caused problems\nbefore. Using a spinlock should be at least as good\nas the BKL in theory, but who knows...\n\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Matthew Wilcox \u003cwilly@linux.intel.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

The callback is\nperformed before each freeing of an object.\n\nI would think that it is much easier to check the object state manually\nbefore the free. That also places the check near the code object\nmanipulation of the object.\n\nAlso the SLAB_DEBUG_INITIAL callback is only performed if the kernel was\ncompiled with SLAB debugging on. If there would be code in a constructor\nhandling SLAB_DEBUG_INITIAL then it would have to be conditional on\nSLAB_DEBUG otherwise it would just be dead code. But there is no such code\nin the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real\nuse of, difficult to understand and there are easier ways to accomplish the\nsame effect (i.e. add debug code before kfree).\n\nThere is a related flag SLAB_CTOR_VERIFY that is frequently checked to be\nclear in fs inode caches.
