Re: [Libguestfs] [PATCH nbdkit 1/2] server: extents: Set errno on error from nbdkit_add_extent.

errno is currently set to a suitable value if nbdkit_extents_new returns an error, but this was not documented so I added that documentation. Set errno to a suitable value if nbdkit_add_extent returns an error, and also document that. Thanks: Eric Blake for spotting the problem. --- docs/nbdkit-filter.pod | 3 ++- docs/nbdkit-plugin.pod | 2 +- server/extents.c | 2 ++ 3 files changed, 5 insertions(+), 2 deletions(-)
