2013-07-18Fix possible race condition in readlink.2 exampleChuck Coffing1-1/+1
I noticed that the example in the readlink.2 man pages does error checking for a race condition that would cause the value of the symbolic link to get larger. However, it doesn't handle the opposite case, in which the value gets shorter. (The NULL terminator is always set at the old, longer offset.) This could cause the program to operate on uninitialized data. Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>

2013-07-18perf_event_open.2: Update PERF_IOC_FLAG_GROUP infoVince Weaver1-11/+13
It turns out PERF_IOC_FLAG_GROUP was broken from 75f937f24bd9 (in Linux 2.6.31, the initial perf_event release) until 724b6daa1 (Linux 3.4). I've done some extensive kernel source code digging plus running tests of various kernels and I hope the info presented is accurate now. (Patch edited somewhat by mtk.)
