Xiang Xiao	e3f23b5bca	drivers/syslog/syslog_putc.c: call sc_force in idle task even interrupt buffer enabled. The following cases may hang randomly in the bring up phase: (1) boot up process and (2) suspend/resume process. Either case runs in the idle task context, so it's difficult to debug the hang issue if these output go through the interrupt buffer.	2018-11-09 08:39:26 -06:00
Gregory Nutt	cf1375daf7	Break syslog_channel.c up into syslog_channel.c, syslog_putc.c, syslog_force.c and syslog_flush.c to limited what is brought into the link. Separate syslog_emergstream.c from syslog_stream.c. Didn't help in the case I was looking at.	2016-06-20 17:10:52 -06:00
