Steven Rostedt 07c3f391bc tracing: Remove EVENT_FILE_FL_SOFT_MODE flag ... When soft disabling of trace events was first created, it needed to have a way to know if a file had a user that was using it with soft disabled (for triggers that need to enable or disable events from a context that can not really enable or disable the event, it would set SOFT_DISABLED to state it is disabled). The flag SOFT_MODE was used to denote that an event had a user that would enable or disable it via the SOFT_DISABLED flag. Commit 1cf4c0732d ("tracing: Modify soft-mode only if there's no other referrer") fixed a bug where if two users were using the SOFT_DISABLED flag the accounting would get messed up as the SOFT_MODE flag could only handle one user. That commit added the sm_ref counter which kept track of how many users were using the event in "soft mode". This made the SOFT_MODE flag redundant as it should only be set if the sm_ref counter is non zero. Remove the SOFT_MODE flag and just use the sm_ref counter to know the event is in soft mode or not. This makes the code a bit simpler.
