Hello,
I need to compute a crc32 in my small not-ready-for-the-prime-time patch against 2.4.19-pre. I do not (yet) follow the 2.5 development.
There is <linux/crc32.h> that does what I want, but not quite effectively and with comments that it is unsuitable for bulk data and that it will migrate to net/core/crc.c.
There are table-driven /usr/src/linux-2.4.19/fs/jffs2/crc32.*, but this code is hidden in a filesystem subtree.
Any plans to do it "the right way" in 2.4? Is net/core (mentioned in the crc32.h) the right place? - as we see it is used also in the filesystem code and lib would be probably a better place.
I can post a patch, but I cannot test whether it breaks jffs2 and as this adds 1 kB to the kernel that might not be needed I would like to ask first. Who is hacking these parts?
Regards -- Stano
