Hello Everybody, Actually I forgot to mention the kernel I'am working on, it is Montavista Kernel 2.4.19. In 2.4.19 there is not support for dm_crypt i.e CONFIG_DM_CRYPT. Hence for encryption/decryption , the hooks raid5_make_request and raid5_end_read_request are suggestable or not. Please suggest an approach. Thanks & Regards Chaitanya. --- Luca Berra <bluca@xxxxxxxxxx> wrote: > On Tue, Sep 13, 2005 at 10:14:47PM -0700, vinnakota > chaitanya wrote: > >Hello Friends, > > > >I'am working on a "RAID 5 Controller" device to > which > >4 SATA hard drives are connected each of size 80GB. > > > >My requirement is implementing encryption & > >decrpyption for the device.
