commit 30fac0f75da24dd5bb43c9e911d2039a984ac815 Author: Jan Kara <j...@suse.cz> Date: Sun Dec 8 21:11:59 2013 -0500 ext4: Do not reserve clusters when fs doesn't support extents ** Changed in: linux (Ubuntu Trusty) Status: In Progress => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1248270 Title: Please set CONFIG_EXT3_FS=n and CONFIG_EXT2_FS=n and CONFIG_EXT4_USE_FOR_EXT23=y Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Released Bug description: When the old code is disabled the ext4 driver takes over and does a better job and gives a smaller kernel. Specifically the ext4 driver does a better job of resisting fragmentation since it uses delayed allocation, and supports online resize, whereas the ext2 driver does not. Config changes requested: CONFIG_EXT3_FS=y -> n CONFIG_EXT2_FS=y -> n CONFIG_EXT4_USE_FOR_EXT23 (NEW) -> y To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1248270/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
