Subject: perf hists browser: Fixup the "cpu" column width calculation
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a4978eca684a3b471f3da862f427e419283e93a3;p=linux-beck.git

perf hists browser: Fixup the "cpu" column width calculation

Since we were not setting it to at least 3 chars ('CPU'), it was being
reset to zero when recalculating the columns width when refreshing the
screen, in 'perf top'. Fix it.
