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:

[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
