MTD files MIA, and strange permission failure

MTD files MIA, and strange permission failure

[Siders, Keith]

I downloaded all new from CVS on Friday and am attempting to recompile the
our MIPS kernel with JFFS2 support. Permissions are 777 all the way up to
/usr down both the /usr/src/mtd path and the /usr/src/linux path to which so
much of the mtd path is linked, yet I get this error.

> make[4]: Entering directory `/usr/src/linux/drivers/mtd/chips'
> touch: /usr/src/include/linux/mtd/compatmac.h: Operation not permitted
> make[4]: *** [/usr/src/linux/include/linux/mtd/compatmac.h] Error 1

Also, files cfi_jedec.c and mapped.h are none existent, but of course the
patchin.sh script created softlinks for them anyway. The MTD and JFFS2
section of .config is as follows:

Have I missed configured something here??

Found that even though a root owned file and path are set for full access by
anyone, touch still won't work. Did chgrp and chown, and that part now
compiles. But now that I'm in fs/jffs I'm getting the following:
----------------------------------------------------------------------------

make: *** [_dir_fs] Error 2
----------------------------------------------------------------------------

Files that were previously reported as missing ( cfi_jedec.c and mapped.h )
didn't seem to effect the mtd compilation. But now that we're in the fs we
get the above. Can't find a linux/completion.h anywhere. Is this particular
to a distribution? We appear to be using a MIPS port of RedHat 7.0. Console
comes up showing:

Red Hat Linux release 7.0 (MIPS)
Kernel 2.4.6 on a mips

Any pointers appreciated...

Completions turned up in 2.4.8, I think. Should be compatibility cruft in 
include/linux/compatmac.h though.

Are you intentionally using JFFS instead of JFFS2?
