In fact it was broken by followng commit >From 03ba3782e8dcc5b0e1efe440d33084f066e38cae Mon Sep 17 00:00:00 2001 From: Jens Axboe <jens.axboe@xxxxxxxxxx> Date: Wed, 9 Sep 2009 09:08:54 +0200 Subject: [PATCH] writeback: switch to per-bdi threads for flushing data The problem with __sync_filesystem(0) is no longer works on umount because sb can not be pined s_mount sem is downed for write and s_root is NULL. And in fact ext3 is also broken in case of "-obarrier=1" The patch attached fix the original regression, but there is one more issue left A delalloc option. In fact dirty inode is still dirty even after first call of writeback_single_inode which is called from __sync_filesystem(0) due to delalloc allocation happen during inode write. So it takes second __sync_filesystem call to clear dirty flags. Currently i'm working on that issue. I hope i'll post a solution today. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
