It is supported both in the sense of being contained in mips version of statfs/statfs64 structs and also in the sense that it's filled by the corresponding kernel syscalls.
It is UNsupported in that sense that it's value is the same as that of f_bsize (at least on older kernel versions, the oldest version tested is 2.6.13), s. [1] and [2] for details ([1] is the latest kernel version as of now, [2] is the oldest kernel version git history is available for).

Thanks for the patches, I applied and pushed all three. They are part of the latest release.
best regards Waldemar
