* libsmartcols: clean up flags usageKarel Zak2014-04-031-3/+3
| | | | | | | | | * rename flags functions to scols_table_enable_* * rename *_no_foo() functions to _nofoo() * output formats are mutually exclusive, so don't use flags there * don't assume symbols in scols_new_table(), use scols_table_set_symbols() Signed-off-by: Karel Zak <kzak@redhat.com>

* swapon: allow a more flexible swap discard policyRafael Aquini2013-08-231-21/+72
| | | | | | | | | | | | | | | | | | | | Introduce the necessary changes to swapon(8) allowing a sysadmin to leverage the new changes introduced to sys_swapon by "swap: discard while swapping only if SWAP_FLAG_DISCARD_PAGES", therefore allowing a more flexible set of choices when selection the discard policy for mounted swap areas. This patch introduces the following optional arguments to the already existent swapon(8) "--discard" option, in order to allow a discard type to be selected at swapon time: * once : only single-time area discards are issued. (swapon) * pages : discard freed pages before they are reused. If no policy is selected both discard types are enabled. (default) [kzak@redhat.com: - support <policy> argument for short -d option too, - add errx() on unsupported policy name] Signed-off-by: Rafael Aquini <aquini@redhat.com> Acked-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: add mnt_table_is_empty(), improve table list usageKarel Zak2013-08-201-2/+4
| | | | | | | | Currently you have to use mnt_table_remove_fs() + mnt_free_fs() to destroy the list in the table. This is complicated in same situations. This patch allows to use mnt_free_fs() only. Signed-off-by: Karel Zak <kzak@redhat.com>

* swapon: add --show optionSami Kerola2012-07-101-1/+186
| | | | | | | | | | | | The --show uses lib/tt.c, which allows user to specify columns he is interested of, and avoids using hard coded field sizes which may be problematic when system has large enough swap.

* checkxalloc: nudge regex, fix newfound instancesDave Reisner2012-03-201-4/+2Star
| | | | | | | | | | | | | | | | Using the -w flag with grep actually fought against us here, and hid some instances where xalloc functions weren't used. Discard it in favor of an explicit word boundary as a prefix to the function name, and extend our requirements on the trailing side of the pattern. This also fixes the few new instances that were overlooked because of the regex's deficiency.
