Subject: xfs: don't reallocate sxp variable passed into xfs_swapext
From: Eric Sandeen <sandeen@xxxxxxxxxxx>
Addresses http://bugzilla.kernel.org/show_bug.cgi?id=12538, "xfs_fsr fails
on 2.6.29-rc kernels"
Regression caused by 743bb4650da9e2595d6cedd01c680b5b9398c74a ("[XFS] Move
copy_from_user calls out of ioctl helpers into ioctl switch").
This was an embarrasing mistake, reallocating the sxp pointer passed in
from the main ioctl switch.
