Hi Miklos, After merging the overlayfs tree, today's linux-next build (powerpc ppc64_defconfig) produced this warning:
fs/overlayfs/dir.c: In function 'ovl_rename': fs/overlayfs/dir.c:1060:2: warning: 'newdentry' may be used uninitialized in this function [-Wmaybe-uninitialized] dput(newdentry); ^ fs/overlayfs/dir.c:1062:2: warning: 'olddentry' may be used uninitialized in this function [-Wmaybe-uninitialized] dput(olddentry); ^ Introduced by commit 02cac3227a28 ("ovl: mark upper dir with type origin entries "impure"") -- Cheers, Stephen Rothwell
