* umount: (recursive) don't call umount(2) for already unmounted targetsKarel Zak2012-11-152-12/+40
| | | | | | | | | In the umount --recursive we follow entries from mountinfo, but the entries maybe already obsolete. Especially if the hierarchy of the mountpoints contains shared subtrees and umount(2) for one entry may generate umount for some other entry too. Signed-off-by: Karel Zak <kzak@redhat.com>

* lscpu: Fix issue found on CPU hot-removeToshi Kani2012-11-121-22/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | read_basicinfo() relies on sysfs cpu directories "/sys/devices/system/cpu/cpu%d" with assumption that cpu logical number %d is always sequentially assigned for all CPUs. However, this assumption is not correct with CPU hot-remove operation since it removes a target sysfs cpu directory after it is ejected. As a result, lscpu may not recognize all CPUs. The issue can be easily reproduced on KVM or VirtualBox, which supports CPU eject operation, as follows. 1) The system has 4 CPUs $ lscpu -a -e CPU NODE SOCKET CORE L1d:L1i:L2 ONLINE 0 0 0 0 0:0:0 yes 1 0 1 1 1:1:1 yes 2 0 2 2 2:2:2 yes 3 0 3 3 3:3:3 yes 2) Eject cpu2 # echo 1 > /sys/bus/acpi/devices/LNXCPU:02/eject 3) lscpu no longer recognizes cpu3 after cpu2 is ejected $ lscpu -a -e CPU NODE SOCKET CORE L1d:L1i:L2 ONLINE 0 0 0 0 0:0:0 yes 1 0 1 1 1:1:1 yes The following changes are made to address this issue. - Use maxcpus to allocate and parse bitmaps. - Set desc->ncpu from cpu/present, which includes both on-line and off-line CPUs. - Add is_cpu_present() to check if a CPU is present. Ejected CPUs are not present. [kzak@redhat.com: - read also /sys/devices/system/cpu/possible mask to determine maximal number of CPUs, - err() if possible mask is not found in /sys] Signed-off-by: Toshi Kani <toshi.kani@hp.com> Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | The commit cdd2a8c360c70d16804ace7cc923a6c6bb7c9ca9 broke script(1) return value. $ script -e -c "echo"; echo $? 1 The reason, as Daniel it reported, was that the script will close stderr twice, once as timing file and atexit() in function close_stdout().
