Subject: [PATCH] tests: fix ACL-printing tests
Date:   Mon, 28 Feb 2022 21:17:06 -0700
Message-Id: <20220301041706.75079-1-adilger@whamcloud.com>

Fix the ACL-printing tests to be more flexible for different systems.
If the MKFS_DIR is on tmpfs, it will not list "system.posix_acl*"
xattrs, so they will not be copied.  Create this on a real filesystem
or skip the test if that doesn't work.

Filter out the security.selinux xattr if it is printed, since this
depends on the selinux configuration of the host system.  However,
this also spills xattrs for "acl_dir/file" into an external xattr
block, and causes it to fail due to different block allocations.
Increase the filesystem inode size so that the allocation is the same
regardless of whether selinux is enabled or not.

Fixes: 67e6ae0a35 ("mke2fs: fix a importing a directory with an ACL")
