+# Test statx
+#
+# This code tests if the attributes field of statx received expected value.
+# File set with following flags by using chattr and encrypt:
+# 1) STATX_ATTR_COMPRESSED - The file is compressed by the filesystem.
+# 2) STATX_ATTR_IMMUTABLE - The file cannot be modified.
+# 3) STATX_ATTR_APPEND - The file can only be opened in append mode for writing.
+# 4) STATX_ATTR_NODUMP - File is not a candidate for backup when a backup program
+# such as dump(8) is run.
+# 5) STATX_ATTR_ENCRYPTED - A key is required for the file to be encrypted by
+# the filesystem.
+#
+# A test directory is created with a file in it.
+# chattr command is used to modify the atttributes of the file such as
+# compressed, append, nodump and immutable.
+# tune2fs tool is used to set the encrypt flag.
+# Two files are tested.
+# First file has all flags set.
+# Second file has no flags set.
+# A helper function in C is used to execute statx syscall.
+#
+# Minimum Kernel version required is 4.11.

* statx01.c: This file will check metadata of files like uid, gid, size, blocks, mode for normal file(1) and rdev_major, rdev_minor number for device file(2) * statx02.c: This file will check flag like AT_EMPTY_PATH, AT_SYMLINK_NOFOLLOW * AT_EMPTY_PATH: If pathname is an empty string, operate on the file referred to by dirfd. * AT_SYMLINK_NOFOLLOW:If pathname is a symbolic link, do not dereference it: instead return information about the link itself. * stat03.c: This file will check error code(errno) by providing required input in statx argument syscall. The following errno are checked: EBADF, EBADF, ENAMETOOLONG, ENOENT, ENOTDIR, EFAULT. * statx04.sh: This script will check attribute flag by defining flag to that directory and checks another directory no flags.
