Hi, this series is a resend of my pending patches which I sent some days ago. For the recent dlm tracepoint patches I did some changes, see below.
changes in "fs: dlm: initial support for tracepoints": - switch from e.g. uin32_t/u32 to __u32 in dlm tracing header as I figured out that this is common used. However it seems it really doesn't care, they are not uapi headers. - switch from %d to %x printout for lkb_id as it is used for dlm debugfs. The lockspace id is still %d as it is used for sysfs. - move trace_dlm_lock_start after error, we don't trace the error and we need to garuantee that lkb pointer is not dangled. - add tracepoint start/end for dlm_unlock aswell, otherwise there are ast callbacks which are not recognizable, especially on DLM_EUNLOCK inside the status block. - add a note that dlm_lock/unlock_start will only be traced if ls/lkb is valid. I think it makes no sense without any reference to do any lock/unlock tracing. - Alex Alexander Aring (4): fs: dlm: implement delayed ack handling fs: dlm: fix return -EINTR on recovery stopped fs: dlm: initial support for tracepoints fs: dlm: trace socket handling fs/dlm/ast.c | 4 + fs/dlm/dir.c | 4 +- fs/dlm/lock.c | 10 ++ fs/dlm/lowcomms.c | 5 + fs/dlm/lowcomms.h | 1 + fs/dlm/main.c | 3 + fs/dlm/member.c | 4 +- fs/dlm/midcomms.c | 56 +++++++-- fs/dlm/recoverd.c | 4 +- include/trace/events/dlm.h | 252 +++++++++++++++++++++++++++++++++++++ 10 files changed, 332 insertions(+), 11 deletions(-) create mode 100644 include/trace/events/dlm.h -- 2.27.0
