Subject: [PATCH] perf tools: handle spaces in file names obtained from /proc/pid/maps
Date: Fri, 1 Jan 2016 04:03:21 +0100	[thread overview]
Message-ID: <20160101030321.GA2217@marcin-Inspiron-7720> (raw)

Steam frequently puts game binaries in folders with spaces.

Note: "(deleted)" markers are now treated as part of the file name.

It probably worked before 6064803313bad9ae4cae233a9d56678adb2b6e7c
("perf tools: Use sscanf for parsing /proc/pid/maps").
