As we have forked the ext4 filesystem and JBD2, this is an update the previously known as 48bit ext3 patches changes since last time: -rebase all previous ext3 patches to against ext4/jbd2 -fixed an reservation window intialization issue with extent block allocation and merge the change to the parent patch:ext4-extents.patch -merged prevous bug fixes patches from sct for 64 jbd2 to their parent patch:64bit-jbd2-core.patch -merged ext3-extents-fsblk_t patch to ext4-extents-48bit.patch -merged 64bit-incompat-flag-change.patch ext3-sb-struc-sync-with-e2fsprog.patch to parent patch 64bit-metadata.patch A complete series of patches (including forking ext4 filesystem patches and 48bit patches submitted here) could be found at: http://ext2.sourceforge.net/48bitext3/patches/latest/ To test the new ext3dev filesystem, just mount the filesystem with -t ext3dev. By default ext3dev is still running 32 bit mode and without extents. To testing extents and 48bit block number, need -o extent mount option. (Maybe we should enable extent as default for ext3dev filesystem ?) Tested these patches on i386 and passed a few hours fsx test.
