This patch series is extracted from http://ftp.de.debian.org/debian/pool/main/g/genext2fs/genext2fs_1.4.1-4.debian.tar.gz The patches are used in Debian for quite a long time, so I assume that this is solid material. At least, my Ubuntu host fsck.ext4 does not bark :-) The goal is to allow building filesystems with larger blocksizes instead of the current default of 1k. This should improve performance and lifetime when the filesystem is stored e.g. on a SD card (on Raspberry Pi/I2SE Duckbill for example) which uses internal flash memory. Writing to flash memory is slow because writing the data of one block results in erasing a whole erase block of the flash memory. Thus it is preferable to align the filesystem block size on a flash device with the erase blocksize, or at least bring it closer to the later one, to avoid unnecessary write amplification.
