- Core locking primitives updates: - Remove mutex_trylock_recursive() from the API - no users left - Simplify + constify the futex code a bit - Lockdep updates: - Teach lockdep about local_lock_t - Add CONFIG_DEBUG_IRQFLAGS=y debug config option to check for potentially unsafe IRQ mask restoration patterns. (I.e. calling raw_local_irq_restore() with IRQs enabled.) - Add wait context self-tests - Fix graph lock corner case corrupting internal data structures - Fix noinstr annotations - LKMM updates: - Simplify the litmus tests - Documentation fixes - KCSAN updates: - Re-enable KCSAN instrumentation in lib/random32.c - Misc fixes: - Don't branch-trace static label APIs - DocBook fix - Remove stale leftover empty file Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAmAs//sRHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1im+g/9G8taVrfiBQ7hg4PoEo28w8fzu5pGBOWd rYzUNJO96dW262FbQE6txGDBeGEahnVTz1sGwqKcy1NfZgQBCWj4uZMOluyECrY3 SV8Iccz2+M6CV+pyjM6Agm7OrgEHxlB/oorZy3TD6s2YeuR6nVGfO3vAXbNNeAsk N8TR5mKY8ELbKXkjrc4KauOOiaqsQmVMuV/l/1DLoydDxATYq4Fczh0lcIdwMtYB pqzWAKa0Qy2mKcHXe2YMYjddn2JEcDWNGJCsmZTa6m45aaAW1XyICLLxcQ2X8aL+ aj9rxYTBkZl9vAjrICfbJTtYku6fN48JiDoNRQxUShGVmVKAlHxYQ4vZ7dJz0NHz EdRrd9JIr25ImXNHlX2KCKGc/aUm4TvDtNVXCdxVlZGwnEEF8J5VocWKRKmXmA1W MkAvPnXnynqRfcMkFaTtTfdMTan41uEixwEnUy++JTuNSMx2ie3VGMC0MgxvTBiH iKN5iVtZVa1mUN2593Jd1qdZvGQMeIydMj+WaT4xh5hptjLCGLg4yPgYuoO7vNMT uEfv8oODvTN8BqEixNP1Ef9pzxujuSiPoO4ZO4DNnbJJZVw1TwAZIK5Zz1wR1Zso Wf1LKPaEOyqz5cFAJ/OxcnxvxMv3fat0vhLNzJlBEFEgKmfRhbsQVUNNL1AcdMJA +Npbj/v5seo= =BYju -----END PGP SIGNATURE----- Merge tag 'locking-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Ingo Molnar: "Core locking primitives updates: - Remove mutex_trylock_recursive() from the API - no users left - Simplify + constify the futex code a bit Lockdep updates: - Teach lockdep about local_lock_t - Add CONFIG_DEBUG_IRQFLAGS=y debug config option to check for potentially unsafe IRQ mask restoration patterns.
