Subject: [PATCH] don't reallocate sxp variable passed into xfs_swapext
Date: Sun, 25 Jan 2009 20:53:00 -0600 [thread overview]
Message-ID: <497D258C.1000908@sandeen.net> (raw)
fixes kernel.org bugzilla 12538, xfs_fsr fails on 2.6.29-rc kernels
Regression caused by 743bb4650da9e2595d6cedd01c680b5b9398c74a
This was an embarrasing mistake, reallocating the sxp pointer passed
in from the main ioctl switch.
