Subject: do_coredump: fix the "ispipe" error check
X-Git-Tag: v3.1-rc1~197
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=99b64567486716d18b2156cad188d86478816e4f;p=pandora-kernel.git

do_coredump: fix the "ispipe" error check

do_coredump() assumes that if format_corename() fails it should return
-ENOMEM.  This is not true, for example cn_print_exe_file() can propagate
the error from d_path.  Even if it was true, this is too fragile.  Change
the code to check "ispipe < 0".
