Date: Wed, 27 May 2009 15:01:07 +0200 From: Jan Kara <jack@...e.cz> To: LKML <linux-kernel@...r.kernel.org> Cc: npiggin@...e.de, linux-ext4@...r.kernel.org, Jan Kara <jack@...e.cz> Subject: [PATCH 10/11] vfs: Export wakeup_pdflush When we are running out of free space on a filesystem, we want to flush dirty pages in the filesystem so that blocks reserved via delayed allocation get written and unnecessary block reservation is released. Export wakeup_pdflush() so that filesystem can start such writeback.
