PATCH 1/1 Bug 603827 - GFS2: BUG in gfs2_adjust_quota
This patch is for inclusion upstream.
HighMem pages on i686 do not get mapped to the buffer_heads and this was causing a NULL pointer dereference when we were trying to memset page buffers to zero.
We now use zero_user() that kmaps the page and directly manipulates page data. This patch also fixes a boundary condition that was incorrect.
