Subject: [PATCH v2 00/13] btrfs-progs: Make W=1 great (no "again")
Date: Wed,  5 Dec 2018 14:40:05 +0800
Message-ID: <20181205064018.27755-1-wqu@suse.com> (raw)

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" great (may 'again' or not, depending on the
distribution rolling speed).

changelog:
v1.1:
- Use cc-disable-warning instead of putting -Wno-something to improve
  compatibility.
- Better explaination on the BUG_ON() branch caused uninitialized
  variable.
- Also cleanup free-space-tree.c

v2:
- Add reviewed-by tags, except the 7th patch, as it goes a different way
  to fix in v2.
- Fix bad port of cc-disable-warning, using $CFLAGS instead of kernel
  flags.
- Make sure fixed warnings still show in W=3.
- Use do {} while() loop to replace a while() {} loop, so even compiler
  doesn't have enough hint for BUG_ON(), it won't report uninitialized
  variable warning.
