* blkdiscard: new commandKarel Zak2012-09-273-36/+194
| | | | | | | | | | | Add to fstrim(8) code to support new discard BLKDISCARD and BLKSECDISCARD ioctls for block devices. The new command is only symlink to fstrim(8) as the both utils share some code and the basic ideas. Based on patch from Lukas Czerner <lczerner@redhat.com>. Signed-off-by: Karel Zak <kzak@redhat.com>
* hwclock: don't warp the systemtime if the RTC is in UTCTom Gundersen2012-09-212-6/+22
| | | | | | | | | | | | | | | | | A sideeffect of 839be2ba6b44fa9dc927f081d547ebadec9de19c is that we now warp the systemtime according to the timezone, on the first call of --systz. This is not always the correct thing to do, and causes a regression for us in Arch Linux. The behavior is correct if the RTC, and hence the systemtime, is in localtime. However, if the systemtime is already in UTC we don't want to touch it when we set the kernel timezone (which we still need to do as some filesystems use this information). An almost identical issue was also fixed in systemd commit 72edcff5db936e54cfc322d9392ec46e2428fd9b. Signed-off-by: Tom Gundersen <teg@jklm.no>

* mount: losetup: remove obsolete encryption supportLudwig Nussel2012-09-114-96/+12Star
| | | | | | | | | | | | | | | kernel cryptoloop is deprecated since ages and support for cryptoloop in util-linux is incomplete/broken. - no password hashing - last 8 bit of key are always set to zero - no binary keys possible (stops reading key at \n and \0) In the past some Distros added the above features with patches. So remove cryptoloop support from util-linux completely to make sure people won't try using it. Signed-off-by: Ludwig Nussel <ludwig.nussel@suse.de> Signed-off-by: Karel Zak <kzak@redhat.com>

* docs: add sys-utils/umount.8 manual pageSami Kerola2012-08-062-1/+176
| | | | | | | | | | The man page is almost exact copy of mount-deprecated/umount.8. This version mentions long options, and has the options in same order as they are mentioned in usage() output. Rest of the minor changes make groff slightly nicer e.g. use .PP instead of empty line for paragraph marker. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* mount: replace control chars in mountpoint nameKarel Zak2012-08-062-8/+27
