Subject: [linux-next:master 3022/3360] fs/btrfs/extent-tree.c:2540:5: sparse:
symbol 'btrfs_run_delayed_refs_for_head' was not declared. Should it be
static?
tree: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head: 43783a8f68478e81fe183f86162d3e7ca29ba923
commit: ac75a14eb672441d674d46b64a03f59d0f186cae [3022/3360] btrfs: Factor out loop processing all refs of a head
reproduce:
# apt-get install sparse
git checkout ac75a14eb672441d674d46b64a03f59d0f186cae
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__
