Hi, Erez, Thanks for your advice, I turn off the CONFIG_UNION_FS_XATTR and the compile error "implicit declaration of function 'vfs_listxattr'" goes away. Thank you so much. The compilation was on kernel directory patched with unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz (file size 241K) sent by Fernando Gomes.
I also want to feed back to you on the patch file you just created unionfs-2.3.3_for_2.6.18-RHEL5.diff.gz (file size 88K). The patch command on this diff file generated some errors (See patch.out). I don't know if the patch failures are caused by the minor revision difference on the RHEL5 (My RHEL5 has kernel version of 2.6.18-8, the kernel tarball that Konard provided to you has version of 2.6.18-53 - RHEL5.1 kernel), or the patch failures are caused by other things. Anyway, for the time being, I will patch with unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz, compile with CONFIG_UNION_FS_XATTR turned off, and will be moving to the testing phase of unionfs soon. If you happen to create another version of unionfs-2.3.3_for_2.6.18-RHEL5.diff.gz, I will be glad to test it for you. Once again, thanks to everyone that helped with this patching problem.

Thanks in advance. > > Andy Ngo Andy, there's no xattr support in unionfs for 2.6.18 (the VFS was lacking some vital support, I don't recommend it). So plz turn off CONFIG_UNION_FS_XATTR. Anyway, thanks to Konrad's rhel5 tarball, I produced now a unionfs-2.3.3 patch which applies and compiles cleanly on rhel5.
