Joel, Looking at your documentation for the new "reflink" syscall (to create copy-on-write files): http://git.kernel.org/?p=linux/kernel/git/jlbec/ocfs2.git;a=blob;f=Documentation/filesystems/reflink.txt;h=58a6b3879114c0cb591fb736152b30291037edd2;hb=c04db1c934e67337318b177688c0b882297fdd66 Have you looked at whether this is close enough to the existing (e.g. Windows NTFS) copy-on-write syntax/feature so that we could use it under Samba (and on the client side from cifs and in the future smb2). Windows added copy-on-write about 9 or 10 years ago and uses it extensively. although I have not researched enough to see what creating these would look like over the network. -- Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
