Subject: don't reallocate sxp variable passed into xfs_swapext
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f0e0059b9c18426cffdcc04161062251a8f9741e;p=linux-2.6-omap-h63xx.git

don't reallocate sxp variable passed into xfs_swapext

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.
