I made this patch with ver 0.46 . Thanks, == CUT HERE == Subject: [PATCH] cyclictest:Appended man & usage about the same priority of many threads with -h If we run a many threads with -t option, "priority--" rt priority will assign per thread in sequence. But, If we use -h option, all threads is same priority. Append man page and cyclictest usage about the same priority of many threads with -h option. ex) cyclictest -t 5 -p 50 [enter] <-- without -h ex) cyclictest -t 5 -p 50 -h 100 [enter] <-- with -h Signed-off-by: GeunSik Lim Acked-by : Sven-Thorsten Dietrich --- src/cyclictest/cyclictest.8 | 2 +- src/cyclictest/cyclictest.c | 1 + 2 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/cyclictest/cyclictest.8 b/src/cyclictest/cyclictest.8 index 48b2c5e..6059cee 100644 --- a/src/cyclictest/cyclictest.8 +++ b/src/cyclictest/cyclictest.8 @@ -91,7 +91,7 @@ event tracing (used with \-b) Enable function tracing using ftrace as tracer.
