[PATCH 7/7] IMFS: Add fine grained configuration
Sebastian Huber
sebastian.huber at embedded-brains.de
Mon Feb 9 20:35:57 UTC 2015
Remove miniIMFS. Statically initialize the root IMFS.
Add configuration options to disable individual
features of the root IMFS, e.g.
o CONFIGURE_IMFS_DISABLE_CHOWN,
o CONFIGURE_IMFS_DISABLE_FCHMOD,
o CONFIGURE_IMFS_DISABLE_LINK,
o CONFIGURE_IMFS_DISABLE_MKNOD,
o CONFIGURE_IMFS_DISABLE_MOUNT,
o CONFIGURE_IMFS_DISABLE_READLINK,
o CONFIGURE_IMFS_DISABLE_RENAME,
o CONFIGURE_IMFS_DISABLE_RMNOD,
o CONFIGURE_IMFS_DISABLE_SYMLINK,
o CONFIGURE_IMFS_DISABLE_UNMOUNT, and
o CONFIGURE_IMFS_DISABLE_UTIME.
