* fs/*/Kconfig: drop links to 404-compliant http://acl.bestbits.atAdam Borowski2018-01-011-3/+0
| | | | | | | | | | | | | | | | | | This link is replicated in most filesystems' config stanzas. Referring to an archived version of that site is pointless as it mostly deals with patches; user documentation is available elsewhere.

* fs/9p: xattr: add trusted and security namespacesJim Garlick2013-07-081-0/+13
| | | | | | | | | | | | | | | | | | | | Allow requests for security.* and trusted.* xattr name spaces to pass through to server. The new files are 99% cut and paste from fs/9p/xattr_user.c with the namespaces changed. It has the intended effect in superficial testing. I do not know much detail about how these namespaces are used, but passing them through to the server, which can decide whether to handle them or not, seems reasonable. I want to support a use case where an ext4 file system is mounted via 9P, then re-exported via samba to windows clients in a cluster. Windows wants to store xattrs such as security.NTACL. This works when ext4 directly backs samba, but not when 9P is inserted. This use case is documented here: http://code.google.com/p/diod/issues/detail?id=95 Signed-off-by: Jim Garlick <garlick@llnl.gov> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* fs/9p: remove depends on CONFIG_EXPERIMENTALKees Cook2013-01-211-2/+1
| | | | | | | | | | | | | The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

* 9p: remove experimental tag from tested configurationsEric Van Hensbergen2011-05-251-3/+2
| | | | | | | | | The 9p client is currently undergoing regular regresssion and stress testing as a by-product of the virtfs work. I think its finally time to take off the experimental tags from the well-tested code paths. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

* 9p: Add fscache support to 9pAbhishek Kulkarni2009-09-231-0/+9
| | | | | | | | | | | | | | | | | | | This patch adds a persistent, read-only caching facility for 9p clients using the FS-Cache caching backend. When the fscache facility is enabled, each inode is associated with a corresponding vcookie which is an index into the FS-Cache indexing tree. The FS-Cache indexing tree is indexed at 3 levels: - session object associated with each mount. - inode/vcookie - actual data (pages) A cache tag is chosen randomly for each session. These tags can be read off /sys/fs/9p/caches and can be passed as a mount-time parameter to re-attach to the specified caching session.
