Subject: Get rid of exit_syscall pretty printing
X-Git-Tag: v0.3~55
X-Git-Url: https://git.lttng.org/?p=lttngtop.git;a=commitdiff_plain;h=7c15d14a187496b734e553138a7b0ca0fda7ec66

Get rid of exit_syscall pretty printing

It was nice, because it displayed the "= return_code" after a syscall
like strace, but it does not scale when we follow multiple processes on
parallel systems.
