8 * Test statx
9 *
10 * This code tests if the attributes field of statx received expected value.
11 * File set with following flags by using SAFE_IOCTL:
12 * 1) STATX_ATTR_COMPRESSED - The file is compressed by the filesystem.
13 * 2) STATX_ATTR_IMMUTABLE - The file cannot be modified.
14 * 3) STATX_ATTR_APPEND - The file can only be opened in append mode for
15 * writing.
16 * 4) STATX_ATTR_NODUMP - File is not a candidate for backup when a backup
17 * program such as dump(8) is run.
18 *
19 * Two directories are tested.
20 * First directory has all flags set.
21 * Second directory has no flags set.
22 *
23 * Minimum kernel version required is 4.11.
