The patch titled lock validator: special locking: sound/core/seq/seq_device.c has been added to the -mm tree. Its filename is lock-validator-special-locking-sound-core-seq-seq_devicec.patch See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find out what to do about this ------------------------------------------------------ Subject: lock validator: special locking: sound/core/seq/seq_device.c From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx> The ops structure has complex locking rules, where not all ops are equal, some are subordinate on others for some complex sound cards. This requires for lockdep checking that each individual reg_mutex is considered in separation for its locking rules.
