+ Bump UFS1 extended attribute max name length to 256.
+ For extended attribute name max length, kernel filesystem-independant
+ code use either EXTATTR_MAXNAMELEN (BSD API) or XATTR_NAME_MAX (Linux
+ API), which are both defined as KERNEL_NAME_MAX and fits Linux limit
+ of 255 without training \0.
+ UFS1 code had a lower limit that broke Linux compatibility. We can bump
+ the limit without sacrifying backward compatibility, because:
+ 1) There is no API exposing this limit outside the kernel. Upper kernel
+ layers have a larger limit handle the increase without a hitch
+ 2) Each attribute has its own backing store in the fileystem, the name
+ of the backing store matching the attribute name. A newer kernel can
+ create/read/write backing store for longer attribute names and will
+ have no problem with existing shorter names.
