Compiling the Kernel with XFS Support
Whether you applied a patch or obtained an XFS kernel using CVS,
XFS support (CONFIG_XFS_FS) will already be enabled
under the Filesystems submenu. Note that development support is
enabled, as indicated by the experimental options that appear. I’m
using a 2.4.19 kernel in this example, as it is the kernel currently
available via CVS.
File systems ---> [...] <*> SGI XFS filesystem support [ ] Realtime support (EXPERIMENTAL) [*] Quota support [ ] DMAPI support [ ] Debugging support (EXPERIMENTAL) [ ] Pagebuf debugging support (EXPERIMENTAL)
Quota support (CONFIG_XFS_QUOTA) is also
enabled by default, but if you don’t need disk quotas, you can disable
this option. The remaining options provide support for additional
features, and many of them are still experimental. If you don’t
require the specific support that these features provide, it’s best to
leave them disabled.
Real-time support (CONFIG_XFS_RT) allows the
use of a data-only portion of an XFS partition. That means reduced
overhead for metaoperations and results in increased data throughput.
Real-time support is useful for streaming media. Refer to the
xfs(5) manual page for more information.
DMAPI support (CONFIG_XFS_DMAPI) provides an
interface for the Data Management API, which allows XFS to support
hierarchical storage. (Hierarchical storage is an attempt to provide
translucent access between filesystems and backup systems.) For more
information on DMAPI and XFS, refer to http://oss.sgi.com/projects/xfs/dmapi.html ...
