perf tools: Fix possible (unlikely) buffer overflow

2013-01-24T19:40:18+00:00

cppcheck reported: [tools/perf/util/sysfs.c:50]: (error) Width 4096 given in format string (no. 1) is larger than destination buffer 'sysfs_mountpoint[4096]', use %4095s to prevent overflowing it -> All other places in the kernel that use STR(PATH_MAX) have a buffer size of PATH_MAX + 1.

perf tools: Add sysfs mountpoint interface

2012-02-14T01:27:15+00:00

Adding sysfs object to provide sysfs mount information in the same way as debugfs object does. The object provides following function: sysfs_find_mountpoint which returns the sysfs mount mount.
