Hi Chris, et. al, I've recently come across cppcheck (static analyser for C code) and ran it on the current btrfs directory from Linus's repo and it's reported the following potential issues:
linux-2.6$ cppcheck -q fs/btrfs/ [fs/btrfs/compression.c:343]: (error) Data is allocated but not initialized: cb [fs/btrfs/compression.c:583]: (error) Data is allocated but not initialized: cb [fs/btrfs/delayed-ref.c:649]: (error) Data is allocated but not initialized: ref [fs/btrfs/delayed-ref.c:694]: (error) Data is allocated but not initialized: ref [fs/btrfs/extent-tree.c:5766]: (error) Data is allocated but not initialized: extent_op [fs/btrfs/extent-tree.c:5768]: (error) Data is allocated but not initialized: extent_op [fs/btrfs/transaction.c:1161]: (error) Data is allocated but not initialized: ac [fs/btrfs/volumes.c:1387]: (error) Possible null pointer dereference: fs_devices [fs/btrfs/volumes.c:3636]: (error) Memory leak: device Now I'm not really a programmer (much less a kernel one) but I do see people using it discover issues in kernel code. Are these issues real or bugs in cppcheck ? cheers! Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file. Do not panic.
