12 This VFS module is part of the samba(7) suite.
13 The vfs_streams_xattr enables storing of NTFS alternate data streams in
15 the file system. As a normal posix file system does not support the
16 concept of multiple data streams per file, the streams_xattr module
17 stores the data in posix extended attributes (xattrs). The name of
18 these attributes by default is user.DosStream."ADS-NAME". The prefix
19 "user.DosStream." can be changed with the module option
20 streams_xattr:prefix, but be aware that this will also expose those ADS
21 over the SMB extended attributes interface.
22 The file system that is shared with this module enabled must support
24 xattrs.
25 Please note that most file systems have severe limitations on the size
27 of xattrs. So this module might work for applications like IE that
28 stores small zone information in streams but will fail for applications
29 that store serious amounts of data in ADSs.
30 CAUTION: Make sure to set "kernel oplocks = no" in smb.conf if if you
32 use this module because this combination is currently broken. See Bug
33 7537 for details.
34
36 streams_xattr:prefix = STRING
37 Name prefix used when storing an ADS in an xattr, defaults to
38 user.DosStream.. Changing this will also expose ADS over the SMB
39 extended attributes interface.
40 streams_xattr:store_stream_type = [yes|no]
42 Whether the xattr names for Alternate Data Streams of type "$DATA"
43 are suffixed by the stream type string ":$DATA". The default is
44 yes.

53 Source project similar to the way the Linux kernel is developed.
