31 * /mount-point/.streams/XX/YY/aaaa.bbbb/namedstream1
32 * /mount-point/.streams/XX/YY/aaaa.bbbb/namedstream2
34 * where XX/YY is a 2 level hash based on the fsid/inode. "aaaa.bbbb"
35 * is the fsid/inode. "namedstreamX" is a file named after the stream

52 * With the hashing scheme based on the inode we need to protect against
53 * streams showing up on files with re-used inodes. This can happen if we
54 * create a stream directory from within Samba, and a local process or NFS
55 * client deletes the file without deleting the streams directory. When the
56 * inode is re-used and the stream directory is still around, the streams in
57 * there would be show up as belonging to the new file.
59 * There are several workarounds for this, probably the easiest one is on
60 * systems which have a true birthtime stat element: When the file has a later
61 * birthtime than the streams directory, then we have to recreate the
64 * The other workaround is to somehow mark the file as generated by Samba with
65 * something that a NFS client would not do. The closest one is a special
66 * xattr value being set. On systems which do not support xattrs, it might be
67 * an option to put in a special ACL entry for a non-existing group.
