* | lscpu: fix floating point exceptionSami Kerola2019-05-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | As the title tells this change indeed fixes floating point exception, but post processing as value overwrite feels a wrong. Possibly something in input is making cpu set count to go wrong, but I could not get my head around what could it be. Anyway avoiding division by zero seems better than crashing so lets do this atleast for now.

* fstrim: add --quiet option to suppress error messagesSami Kerola2019-05-073-6/+31
| | | | | | | | | | | | | When fstrim interacts with NTFS it result can be error reporting bad file descriptor. That seems to be a bug in NTFS. While waiting driver to get on top of the issue and be commonly available lets add to fstrim option to make it be more silent about errno 9 aka EBADF, Bad file descriptor.

| | | | | | | | | | | Let's consolidate the version printing code. It also seems better to use exit() after --version, because it's handled in different way by ASAN. It's strange, but ASAN reports leaks after return in main(). Note that we do not use free-before-exit. Signed-off-by: Karel Zak <kzak@redhat.com>

* fstrim: get realpath before trim ioctlWang Shilong2019-04-151-2/+9
| | | | | | | | | | | | | | | | | | | | | | Original motivation is we want to run fstrim command on Lustre[1] osd server mount point directly, however our server mount point doesn't export osd directory to users, and it will cause following command fail: $fstrim -v /mnt/mds/ But following succeed: $fstrim -v /mnt/mds We could improve this a bit by getting realpath before trapping kernel, this also give benifits to normal use cases.

* lscpu: report more usable cache sizesKarel Zak2019-03-191-2/+41
| | | | | | | | | | | | | | | | | The current version reports cache size as reported by /sys, it means real size of the one piece of the cache. This way provides minimal overview about all system as the cache is often shared between CPUs. It seems better to report all size of the caches in the summary output. It also does not make sense to report sizes per core (or socket) as CPU topology may be pretty complicated. The final solution (not implemented yet) will be to have --list-caches where we can report all details like all-size, item-size, per-core size, ways, type, etc. Addresses: https://github.com/karelzak/util-linux/issues/663 Signed-off-by: Karel Zak <kzak@redhat.com>
