[LTP] [PATCH v2] Port getxattr01.c to new test API

Mon Sep 18 15:38:19 CEST 2023
* Utilize 'all_filesystems = 1'-mechanism to test on various file
systems instead of relying on the temporary directory's file system
to support xattr (which it probably does not as it is commonly a
tmpfs)
* Improve error handling
* Simplify code and description
* Related issue: https://github.com/linux-test-project/ltp/issues/583

- * Basic tests for getxattr(2) and make sure getxattr(2) handles error
- * conditions correctly.
+/*\
+ * [Description]
*
- * There are 4 test cases:
+ * Basic tests for getxattr(2), there are 3 test cases:
* 1. Get an non-existing attribute,
- * getxattr(2) should return -1 and set errno to ENODATA
+ * getxattr(2) should return -1 and set errno to ENODATA.
* 2. Buffer size is smaller than attribute value size,
- * getxattr(2) should return -1 and set errno to ERANGE
- * 3. Get attribute, getxattr(2) should succeed
- * 4. Verify the attribute got by getxattr(2) is same as the value we set
+ * getxattr(2) should return -1 and set errno to ERANGE.
+ * 3. getxattr(2) should succeed and return the same value we set
+ * before.
