Subject: [PATCH 0/2] trace-cmd/kernel-shark: Use one quick hash algorithm
Date: Fri, 20 Sep 2019 11:15:26 -0400 [thread overview]
Message-ID: <20190920151526.528126066@goodmis.org> (raw)
Instead of having multiple "knuth_hash()" static functions, make one
generic tracecmd_quick_hash() function and use that. It also adds
a "bits" field so that the result can be limited to any power of
2 that is less than 2^32.
Steven Rostedt (VMware) (2):
trace-cmd: Make a global tracecmd_quick_hash() instead of a local knuth_hash()
kernel-shark: Increase the size of the task hash
