Nov 24, 2013 · A successor for JFFS2 exists and is supported by the kernel (UBIFS file system support). The Unsorted Block Image File System (UBIFS) also competes with LogFS. The Linux kernel also supports LogFS (LogFS file system). ROM-based embedded systems need support for CramFS (Compressed ROM file system support (cramfs)).

jffs2 does not support O_DIRECT. You can see in __dentry_open() that in order to support O_DIRECT, a filesystem must supply the direct_IO and/or get_xip_mem members of the address_space_operations struct. You can likewise see that jffs2 does not supply these members. It is not clear why you are so keen to avoid the page cache.

Oct 05, 2010 · Using `mkfs.jffs2 -n` gets rid of the Cleanmarker messages. I have gotten the 2.6.29-omap1 kernel to load a 10M jffs2 filesystem without complaint. The 2.6.36-rc1 kernel complains about the usual ECC errors with the same 10M filesystem. So I guess the problem has something to do with kernel options or kernel source code.

A JFFS2 support for DiskOnChip devices, based on the NAND code, is planned. There are some other Open Source projects for NAND filesystem support, but there's no other working solution than JFFS, YAFFS, and UBIFS at the moment of this writing.
