We don't start writes the instant that pages are dirtied in the buffer cache. In any case, if you have arguments about how the writeback code makes its choices, it's kinda of pointless to be complaining on a bug targetted at the ext4 developers, since we start the writeback when the VM system asks us to start write pages belonging to a particular inode.... See /usr/src/linux/Documentation/sysctl/vm.txt for more information. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
