Hi all,

Here's a couple of patches that make fallocate's ZERO_RANGE the
preferred implementation of unix_zeroout, and rearrange unix_zeroout and
unix_discard to try fallocate first always.  fallocate for block devices
has existed in the kernel for a few years now, and satisfies libext2fs'
requirement that reads following a zero/discard must return zeroes.  The
existing fallbacks for both functions are preserved.

The third patch fixes some build problems due to the MKINSTALLDIRS ->
MKDIR_P transition.

Questions?  Comments?  This series targets e2fsprogs 1.45.

Thanks, I've applied all of the patches in this series.
