[fuse-devel] Some patches for embedded systems...

[Christian M. <chr...@ru...>]

I recently tried to use the latest CVS to my embedded system running
uClinux with uClibc, and I have some suggestions that could be added
just to make it compile for my embedded systems.

The patches won't break anything when the kernel is compiled on a
normal desktop.



I'm compiling it with 2.4.20 and 2.6.9-uc0 without support for sysfs,
and the kernel/dev.c doesn't check if CONFIG_SYSFS is defined. Is it ok
to check that in linux/autoconf.h ?  Does it work for all platforms?

linux/init.h isn't included in kernel/dev.c.

alloc_inode, destroy_inode and inode_init_once is new from kernel
2.4.21. I'm compiling it with 2.4.20 on the WRT54G router.

check_version() should look for "/proc/fs/fuse/version" if
"/sys/fs/fuse/version" doesn't exist.

Timed mutexes doesn't work 100% (which is defaulted from the call
pthread_mutex_init(&m, NULL); ) with uClibc's libpthread support
on Coldfire processors at least.

fork() can't be used if processor is without MMU and uClibc is
compiled without UCLIBC_HAS_MMU define.

mtab and capabilities isn't available for embedded systems with
uClibc. (read-only root-filesystem)
