Changes related to the behavior of the ibound mount option for enhanced XFS:
ibound now allocates additional data, such as extended attributes and directory entries, as well as inodes in the bound area, known as the metadata region. The remainder of the filesystem is known as the user-extent region.
There must be at least as many allocation groups (AGs) in the user-extent region as in the metadata region; for practical purposes, you will normally want more AGs in the user-extent region.
A new allocation strategy employed by ibound, which may be adjusted by using agskip mount option.
The rotorstep system-tunable parameter no longer applies if you are using ibound.
The ibound and inode64 mount options are mutually exclusive; specifying both will now result in an error.
