Module Name: src
Committed By: christos
Date: Sat Sep 3 10:28:33 UTC 2011
Modified Files:
src/sys/kern: kern_sleepq.c
Log Message:
We need to process SA_STOP signals immediately, and not deliver them to
the process. Instead of re-structuring the code to do that, call issignal()
like before in that case. (tail -F /file^Zfg should not get interrupted).
