which contain a realtime subvolume. The realtime subvolume is a
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

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

*
* -Version 1 of this structure (XFS_LI_5_3_INODE) included up to the first

* -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
