If you say Y here you will be able to mount and use XFS filesystems
which contain a realtime subvolume. The realtime subvolume is a
separate area of disk space where only file data is stored. The
realtime subvolume is designed to provide very deterministic
data rates suitable for media streaming applications.
separate area of disk space where only file data is stored. It was
originally designed to provide deterministic data rates suitable
for media streaming applications, but is also useful as a generic
mechanism for ensuring data and metadata/log I/Os are completely
separated. Regular file I/Os are isolated to a separate device
from all other requests, and this can be done quite transparently
to applications via the inherit-realtime directory inode flag.
See the xfs man page in section 5 for a bit more information.
This feature is unsupported at this time, is not yet fully
functional, and may cause serious problems.
See the xfs man page in section 5 for additional information.

* This is the structure of the leaf nodes in the Btree.
*
* Struct leaf_entry's are packed from the top. Names grow from the bottom
* but are not packed. The freemap contains run-length-encoded entries
* for the free bytes after the leaf_entry's, but only the N largest such,
* smaller runs are dropped. When the freemap doesn't show enough space
* for an allocation, we compact the namelist area and try again. If we
* still don't have enough space, then we have to split the block.
*
* Since we have duplicate hash keys, for each key that matches, compare
* the actual string. The root and intermediate node search always takes
* the first-in-the-block key match found, so we should only have to work
* "forw"ard. If none matches, continue with the "forw"ard leaf nodes
* until the hash key changes or the filename is found.
*
* The parent directory and the self-pointer are explicitly represented
* (ie: there are entries for "." and "..").
*
* Note that the count being a __uint16_t limits us to something like a
* blocksize of 1.3MB in the face of worst case (short) filenames.

*
* Convention for naming inode log item versions : The current version

* add the latest version of IRIX that will generate logs with that item
* to the version name.
*
* -Version 1 of this structure (XFS_LI_5_3_INODE) included up to the first
* union (ilf_u) field. This was released with IRIX 5.3-XFS.
* -Version 2 of this structure (XFS_LI_6_1_INODE) is currently the entire
* structure. This was released with IRIX 6.0.1-XFS and IRIX 6.1.
* -Version 3 of this structure (XFS_LI_INODE) is the same as version 2
* so a new structure definition wasn't necessary. However, we had
* to add a new type because the inode cluster size changed from 4K
* to 8K and the version number had to be rev'ved to keep older kernels
* from trying to recover logs with the 8K buffers in them. The logging
* code can handle recovery on different-sized clusters now so hopefully

* for a change in the inode cluster size. This new version was
