Message

This patchset optimizes how pid filters are expressed and makes it less likely
that we overflow ftrace filters' size limit of one page.

Changes since v1:

Add missing tags
Fix append_filter_pid_range() callers to pass valid range as [min,max]

Slavomir Kaslev (2):
  trace-cmd: Optimize how pid filters are expressed
  trace-cmd: Add --no-filter option to not filter recording processes
