fstab can contain tag based mounts. De-duplication by source has to be
done after resolving the full source path.
Perform the table iteration twice. First time, prepare for
de-duplication, second time perform the TRIM itself.

Calling TRIM on some read-only volumes can fail with:
fstrim: /win: FITRIM ioctl failed: Bad file descriptor
Skipping all read-only mounts seems to be safe and logical strategy.
Fixes opensuse#1106214.

"convert LABEL=" does not happens in mnt_fs_get_source(), but later in
mnt_resolve_spec(). To make this more clean, move the comment before this
chunk of code.

If you by accident execute
umount ls -al /mnt/
then umount --all is executed and another arguments silently ignored.
It seems better to be more strict in this case.

Kernel 5.2 can use superblock version 3 for dm-integrity.

With users coming from LDAP, it is often the case that the entry in LDAP
does not contain one or more attributes required by su or, because of
misconfigured access control rights, the attribute might not be readable
by the LDAP client. In that case, su just tells the user that the user
does not exist.
It might be more user-friendly to tell the user to check the user entry
for all required fields.
It's seems people still follow old advices for SSD/4K devices. Let's
make CHS deprecation more visible at the begin of the man page...

We usually check lookup() return value. Let's do it in this case too.
It seems static analyzers will be happy with consistent code.

The ttyname(3) can fail to access /dev/ path, and that will cause function
to fail without setting errno value with result of rather confusing error
message. Lets start setting stdin permission via /proc when this happens as
a go-around, with hope kernel following symlink does not fail. Ok, noted,
that hopes of symlink follow working are pretty slim.
Based on patch from Sami Kerola <kerolasa@iki.fi>.

This started as fix to following warning.
libblkid/src/superblocks/bcache.c:33:3: warning: ISO C99 doesn’t
support unnamed structs/unions [-Wc99-c11-compat]
But when sent to review Karel told out rather than getting rid of warnings
lets get rid of everything unnecessary.
