Prev: [PATCH 2/8] GFS2: Wait for journal id on mount if not specified on mount command line
Next: [PATCH 1/8] GFS2: Use nobh_writepage
From: Steven Whitehouse on 2 Aug 2010 06:00
This reverts commit b7dc2df5725fe7355fd76000ead7e39728e1b8a9.

The initial patch didn't quite work since it doesn't cover all
the possible routes by which the GLF_FROZEN flag might be set.
A revised fix is coming up in the next patch.
