Hi,

I want to enable debugging in unionfs-2.2.4_for_2.6.24.2, but it does not work.

CONFIG_UNION_FS=m
CONFIG_UNION_FS_XATTR=y
CONFIG_UNION_FS_DEBUG=y

This is, how I want to enable debug:
mount -t unionfs -o dirs=/tmp/aaa=rw:/tmp/bbb=ro,debug=1 unionfs /tmp/ccc

But I get:
unionfs: unrecognized option 'debug'

~# modinfo unionfs
filename:       /lib/modules/2.6.24.2-alix-i586/kernel/fs/unionfs/unionfs.ko
license:        GPL

depends:
vermagic:       2.6.24.2-alix-i586 mod_unload 586

I got a warning when compiling the kernel with enabled debugging. Mabe its important:
 CC [M]  fs/unionfs/debug.o
fs/unionfs/debug.c: In function '__unionfs_check_dentry':
fs/unionfs/debug.c:172: warning: passing argument 1 of 'd_deleted' discards qualifiers from pointer target type

Thanks!
Klaus
