From: J. Bruce Fields <bfields@xxxxxxxxxx> This is all out of date. It has some historical interest--but we can leave that in the history. I recently noticed that Fedora was installing this stuff to /usr/share/doc, which can only serve to confuse users. Other distros may be tempted to do the same. Signed-off-by: J. Bruce Fields <bfields@xxxxxxxxxx> --- Apologies, that broke the build! This version also removes references to the deleted directories.

I tend to - mix up EPERM and EACCES. - * NFSv3 support. - - Refuse to look up inodes in procfs (security issues). - o Delayed writes (delay syncing of file data when nfsd handles - several write requests for the same file concurrently). - (Draft - see nfsd_write in fs/nfsd/write.c. Needs benchmarking). - * Faster read operations (single copy): mmap the file region - to be read into VM, and pass the VMA to the xdr routines - which pass the region's VM address into sock->ops->writemsg. - This copies the file data directly from the page cache into - the network buffer. - Release the vma region after encoding. - * Faster write operations (single copy, with IPv6 net layout): - Get the unfragmented UDP datagram, pull the header and - do normal processing. Then mmap the file, copy the write data, - and release VMA. - - Clear setuid/setgid bit after write(). - * Quota support. - -lockd: - - * Server should run on privileged port. - * Testing reclaim support. - * HP lockd accepts our GRANT_MSG callback and passes on the grant - to the blocking process, but doesn't reply with a GRANT_RES. - It's not clear to me why it would do this. - * Unregister hosts (SM_UNMON) with rpc.statd when appropriate. - -mountd - - * Unregister service from portmapper upon exit/SIGTERM - -mount - - * If available, use version 3 of the mount protocol and - obtain pathconf data (fill in data->bsize). - -documentation: - - - Manpages need to be written -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
