** [tickets:#2452] log: mutex lock missing in error cases of
write_log_record_hdl() **
**Status:** review

Unlock is being called twice before waiting hence LOGD crashes.
This because of write_log_record_hdl() is being returned with out
osaf_mutex_lock_ordie(&lgs_ftcom_mutex);
=================================================================================
int write_log_record_hdl(void *indata, void *outdata, size_t max_outsize, bool
*timeout_f) {
int rc = 0;
uint32_t bytes_written = 0;
off_t file_length = 0;
wlrh_t *params_in = static_cast<wlrh_t *>(indata);
/* Get log record pointed by lgs_rec pointer */
char *logrecord = const_cast<char *>(static_cast<const
char*>(params_in->lgs_rec));
int *errno_out_p = static_cast<int *>(outdata);
*errno_out_p = 0;
TRACE_ENTER();
osaf_mutex_unlock_ordie(&lgs_ftcom_mutex); /* UNLOCK Critical section */
retry:
rc = write(params_in->fd, &logrecord[bytes_written],
params_in->record_size - bytes_written);
if (rc == -1) {
if (errno == EINTR)
goto retry;
LOG_ER("%s - write FAILED: %s",__FUNCTION__, strerror(errno));
*errno_out_p = errno;
goto done;
<-------------------------------------------------------------------
} else {
/* Handle partial writes */
bytes_written += rc;
if (bytes_written < params_in->record_size)
goto retry;
}
osaf_mutex_lock_ordie(&lgs_ftcom_mutex);
