[PATCH 2/3] perf tools: Separate shareable part of 'struct map' into 'struct map_shared'

From: Jiri Olsa
Date: Sun Oct 13 2019 - 11:15:40 EST

Next message: Pavel Machek: "Re: [PATCH 4.19 032/114] timer: Read jiffies once when forwarding base clk"
Previous message: Jiri Olsa: "[PATCH 3/3] perf tools: Make 'struct map_shared' truly shared"
In reply to: Jiri Olsa: "Re: [PATCH 3/3] perf tools: Make 'struct map_shared' truly shared"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

This is preparation for truly sharing the 'struct map_shared'.
So far it's statically added inside 'struct map', so there's
no functional change expected other than compilation fail.
