Subject: journald: allow zero length datagrams again
X-Git-Tag: v219~526
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=66518acd40fbd99a87e553b2d0904c37c8929fb2

journald: allow zero length datagrams again

This undoes a small part of 13790add4bf648fed816361794d8277a75253410
which was erroneously added, given that zero length datagrams are OK,
and hence zero length reads on a SOCK_DGRAM be no means mean EOF.
