• 84baf74bf   ROMFS: romfs_lookup() shouldn't be doing a partial name comparison ... Browse Code »

  romfs_lookup() should be using a routine akin to strcmp() on the backing store,
  rather than one akin to strncmp(). If it uses the latter, it's liable to match
  /bin/shutdown when looking up /bin/sh.

• da4458bda   NOMMU: Make it possible for RomFS to use MTD devices directly ... Browse Code »

  Change RomFS so that it can use MTD devices directly - without the intercession
  of the block layer - as well as using block devices.

  This permits RomFS:

  (1) to use the MTD direct mapping facility available under NOMMU conditions if
  the underlying device is directly accessible by the CPU (including XIP);

  (2) and thus to be used when the block layer is disabled.

  RomFS can be configured with support just for MTD devices, just for Block
  devices or for both. If RomFS is configured for both, then it will treat
  mtdblock device files as MTD backing stores, not block layer backing stores.

  I tested this using a CONFIG_MMU=n CONFIG_BLOCK=n kernel running on my FRV
  board with a RomFS image installed on the mtdram test device. I see my test
  program being run XIP:

  # cat /proc/maps
  ...
  c0c000b0-c0c01f8c r-xs 00000000 1f:00 144 /mnt/doshm
  ...

  GDB on the kernel can be used to show that these addresses are within the
  set-aside RAM space.
