i synthesize instructions events b synthesize branches events c synthesize branches events (calls only) r synthesize branches events (returns only) x synthesize transactions events e synthesize error events d create a debug log g synthesize a call chain (use with i or x) l synthesize last branch entries (use with i or x) s skip initial number of events The default is all events i.e. the same as --itrace=ibxe In addition, the period (default 100000) for instructions events can be specified in units of: i instructions t ticks ms milliseconds us microseconds ns nanoseconds (default) Also the call chain size (default 16, max. 1024) for instructions or transactions events can be specified. Also the number of last branch entries (default 64, max. 1024) for instructions or transactions events can be specified. It is also possible to skip events generated (instructions, branches, transactions) at the beginning. This is useful to ignore initialization code. --itrace=i0nss1000000 skips the first million instructions. 'nds-private-remove'>nds-private-remove net-next plumbingsTobias Klauser

audit: Fix sleep in atomic
Audit tree code was happily adding new notification marks while holding spinlocks. Since fsnotify_add_mark() acquires group->mark_mutex this can lead to sleeping while holding a spinlock, deadlocks due to lock inversion, and probably other fun. Fix the problem by acquiring group->mark_mutex earlier. CC: Paul Moore <paul@paul-moore.com> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Paul Moore <paul@paul-moore.com>
