AllLinuxDevices: Announcement: Journaling Flash File System, v2

“Well, it’s been almost a week since the latest stupid bug was
found in the JFFS2 code, so I suppose it’s time to admit to the
world that it exists.”

JFFS2, developed by Red Hat, is a complete reimplementation
of a journalling filesystem for FLASH devices, based on the
original JFFS from Axis Communications AB.

“Improvements of JFFS2 over the original JFFS include:

  • Improved wear levelling and garbage collection
    performance.
  • Compression
  • Improved RAM footprint and response to system memory
    pressure.
  • Improved concurrency and support for suspending flash
    erases
  • Support for hard links.”
