[PATCH 0/9] btrfs-progs: Make W=1 clean (no "again")

[Qu Wenruo <wqu@suse.com>]

This patchset can be fetched from github:
https://github.com/adam900710/btrfs-progs/tree/warning_fixes
Which is based on v4.19 tag.

This patchset will make "make W=1" reports no warning.

This patch will first introduce fix to Makefile.extrawarn to make
"cc-disable-warning" works, then disable sign-compare warning
completely, as we really don't want extra "unsigned" prefix to slow our
typing.

Then re-use (ok, in fact rework) Yanjun's patch to disable
formwat-truncation warning.

Finally, fix all the remaining warnings reported by make W=1.

Now, we make "make W=1" clean (may 'again' or not, depending on the
distribution rolling speed).
