When a task polls waiting for a percentage of the ring buffer to be filled, the writer still will wake it up at every event. Add the polling's percentage to the "shortest_full" list to tell the writer when to wake it up. - For eventfs dir lookups on dynamic events, an event system's only event could be removed, leaving its dentry with no children. This is totally legitimate. But on eventfs_release() it must not access the children array, as it is only allocated when the dentry has children. git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git trace/urgent Head SHA1: 2598bd3ca8dcf5bbca1161ee5b271b432398da37 Beau Belgrave (1): tracing/user_events: Align set_bit() address for all archs Clément Léger (1): tracing: relax trace_event_eval_update() execution with cond_resched() Steven Rostedt (Google) (2): ring-buffer: Update "shortest_full" in polling eventfs: Test for dentries array allocated in eventfs_release() ---- fs/tracefs/event_inode.c | 2 +- kernel/trace/ring_buffer.c | 3 +++ kernel/trace/trace_events.c | 1 + kernel/trace/trace_events_user.c | 58 +++++++++++++++++++++++++++++++++++----- 4 files changed, 56 insertions(+), 8 deletions(-)
