Subject: [XFS] kill INDUCE_IO_ERROR
X-Git-Tag: v2.6.27-rc4~106^2~26
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=1550d0b0b08bc34c0c37a86bd884b1a70782104e;p=linux-2.6-omap-h63xx.git

[XFS] kill INDUCE_IO_ERROR

All the error injection is already enabled through ifdef DEBUG, so kill
the never set second cpp symbol to activate it without the rest of the
debugging infrastructure.
