[Cluster-devel] [PATCH RESEND dlm/next 0/4] fs: dlm: misc and tracing

[Alexander Aring]

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
