I wnated to kick off some testing tonight, so I've made this change to the git tree. So the new version of "reserve metadata block for every delayed write" is here: https://git.kernel.org/cgit/linux/kernel/git/tytso/ext4.git/commit/?h=3D= dev&id=3Dc7cf7abbf754f16b78a8b9641d06baac6be60524 =2E.. and the dev branch has been modified to drop the "reserve metadat= a if writing into unitialized.." commit. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
