CC util-linux/swaponoff.o cc1: warnings being treated as errors util-linux/swaponoff.c: In function 'swap_enable_disable': util-linux/swaponoff.c:100: warning: passing argument 1 of 'resolve_mount_spec' from incompatible pointer type make[1]: *** [util-linux/swaponoff.o] Error 1 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2015-12-16swapon/swapoff: refine the -e (ifexists) optionMike Frysinger
The -e option should only apply to swapon, and it should swallow all errors/warnings when the device does not exist. So delete the flag from the swapoff patch and unify the check in the swapoff path. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2014-03-31swapon/swapoff: size reduction, cleanup, fixes, improvementsTito Ragusa
1) real swapon/swapoff handles also devices on the commandline with -a; 2) xstat(device) in swap_enable_disable aborts on error when cycling through fstab so some devices are not handled; 3) duplicated code for ENABLE_FEATURE_SWAPON_DISCARD and ENABLE_FEATURE_SWAPON_PRI was moved to functions. 4) silence some error messages with -a; 5) minor cleanups and code refactoring reduced the size as per bloat-check: 6) I also added support for /proc/swaps handling to swapoff: "When the -a flag is given, swapping is disabled on all known swap devices and files (as found in /proc/swaps or /etc/fstab)." So now swapoff first cycles through /proc/swaps and then through fstab to swapoff all devices. function old new delta set_discard_flag - 106 +106 swap_enable_disable 147 238 +91 set_priority_flag - 79 +79 retrieve_file_data 470 467 -3 swap_on_off_main 638 418 -220 ------------------------------------------------------------------------------ (add/remove: 2/0 grow/shrink: 1/2 up/down: 276/-223) Total: 53 bytes Signed-off-by: Tito Ragusa <farmatito@tiscali.it> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.
