On a ppc64 big endian system, xfs_db would print the following,
xfs_db> p
core.magic = 0x494e
core.mode = 0100600
core.version = 3
core.format = -253
This is due to fp_dinode_fmt() interpretting the di_format field as
signed. This commit fixes the bug by passing BVUNSIGNED (instead of
BVSIGNED) as the argument to getbitval(). With this commit applied, we
now get,
xfs_db> p
core.magic = 0x494e
core.mode = 0100600
core.version = 3
core.format = 3 (btree)
