[Tarantool-patches] [PATCH v5 0/2] fiber: Handle stack madvise/mprotect errors

[Alexander Turenko]

LGTM (except several minor points; fixes for them are obvious and it is
not necessary to re-review the patchset with me).

Please, fix those points and send the patch to Vlad for the second
review.

WBR, Alexander Turenko.
