Hi Linus, Building Linus' tree, today's linux-next build (powerpc_ppc64_defconfig) produced these warnings: fs/btrfs/backref.c: In function 'find_parent_nodes': fs/btrfs/backref.c:482:3: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] fs/btrfs/backref.c:395:6: note: 'ret' was declared here fs/btrfs/backref.c:381:3: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] fs/btrfs/backref.c:300:6: note: 'ret' was declared here and indeed, there is a path through to a BUG_ON(ret) that does not set "ret". Introduced by commit 8da6d5815c59 ("Btrfs: added btrfs_find_all_roots()"). -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
