I have tried for e2compression support in my system.But it's not fruitful for me. kindly give me the suggestion for my problem.

The Kernel i am using is 2.6.10. I have applied the e2compression patch 0.4.45-alpha2 to that kernel and I have compiled it.
My Root Filesystem is in the ext3 Filesystem. i m also having the ext2 Filesystem drive. In that i have created a directory and i hv set for compression by the following command.
chattr +c $dirname.
After that if i copy any file to that diresctory segmentation Faults occurs.Can i know what is wrong in my side.what should i do to have the ext2 compression File system support.

Thanks in advance.
