Subject: In open(), only set the buffer size from st.st_blksize when it is greater
X-Git-Tag: v3.2a4~332
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ea5d17d9afd3e5eb9ab317665f9d28bd2d59d669;p=thirdparty%2FPython%2Fcpython.git

In open(), only set the buffer size from st.st_blksize when it is greater
than 1.  This matches the pure Python implementation in _pyio and should
fix a couple of failures on the NetBSD buildbot.
