perf hists browser: Increase size of 'buf' in perf_evsel__hists_browse()
Making perf with gcc-9.1.1 generates the following warning: CC ui/browsers/hists.o ui/browsers/hists.c: In function 'perf_evsel__hists_browse': ui/browsers/hists.c:3078:61: error: '%d' directive output may be \ truncated writing between 1 and 11 bytes into a region of size \ between 2 and 12 [-Werror=format-truncation=] 3078 | "Max event group index to sort is %d (index from 0 to %d)", | ^~ ui/browsers/hists.c:3078:7: note: directive argument in the range [-2147483648, 8] 3078 | "Max event group index to sort is %d (index from 0 to %d)", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from /usr/include/stdio.h:937, from ui/browsers/hists.c:5: IOW, the string in line 3078 might be too long for buf[] of 64 bytes. Fix this by increasing the size of buf[] to 128.
