[PATCH 0/5] btrfs-progs: minor fixes for clang warnings

[Qu Wenruo <wqu@suse.com>]

Recently I'm migrating my default compiler from GCC to clang, mostly to
get short comiling time (especially important on my aarch64 machines).

Thus I hit those (mostly false alerts) warnings in btrfs-progs, and come
up with this patchset.

Unfortunately there is still libbtrfsutils causing warnings in
setuptools, as it's still using the default flags from gcc no matter
what.

Qu Wenruo (5):
  btrfs-progs: remove an unnecessary branch to silent the clang warning
  btrfs-progs: fix a false alert on an uninitialized variable when
    BUG_ON() is involved.
  btrfs-progs: fix fallthrough cases with proper attributes
  btrfs-progs: move a union with variable sized type to the end
  btrfs-progs: fix set but not used variables
