(ITS#8976) LMDB > use posix_madvise(3) instead of madvise(3) for SmartOS

Full_Name: Matthieu Guegan
Version: current
OS: SmartOS
Submission from: (NULL) (


In order to compile knot[1] on SmartOS, I have done a series of little patches.
One of them is linked to the LMDB project, which redirects me here.

The idea is to tell SmartOS (and I think the SunOS family) to make use of
posix_madvise(3), instead of madvise(3) as implementation on this OS[2] is
different than, for example, the Linux[3] one.

So, I kindly ask you to take a look at the merge request of the knot project[4],
in particular the `src/contrib/lmdb/mdb.c` patch (that's just a ifdef
modification) : would it be possible to apply this patch directly in this
repository ?
