use #pragma once instead of foo*foo #define guards #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers 2012-07-18 19:07:51 +02:00			`#pragma once`

label: rework label_fix() implementations (#8583) This reworks the SELinux and SMACK label fixing calls in a number of ways: 1. The two separate boolean arguments of these functions are converted into a flags type LabelFixFlags. 2. The operations are now implemented based on O_PATH. This should resolve TTOCTTOU races between determining the label for the file system object and applying it, as it it allows to pin the object while we are operating on it. 3. When changing a label fails we'll query the label previously set, and if matches what we want to set anyway we'll suppress the error. Also, all calls to label_fix() are now (void)ified, when we ignore the return values. Fixes: #8566 2018-03-27 07:38:26 +02:00			`typedef enum LabelFixFlags {`
