[parisc-linux] Re: [fuse-devel] Example filesystem fail to init on parisc

[Miklos Szeredi]

Jick, Chris,

Can you please try the following module containing the simplified
versions of the fuse device read/write routines?

Copy the attached files into an empty directory, then do 'make' and
'insmod copytest.ko'.

Then do

  cat /proc/fs/test
  echo hello > /proc/fs/test
  dmesg | tail

I get something like this:

~$ cat /proc/fs/test
Hello!
~$ echo hello > /proc/fs/test
~$ dmesg | tail
test_read 0804d848 1024 0
dst: 0804d848 page: c13a9f40 offset: 2120 mapaddr: dd4fa000 ptr: dd4fa848
  test_read: 7
test_read 0804d848 1024 7
  test_read: 0
test_write 080e9008 6 0
src: 080e9008 page: c1167560 offset: 8 mapaddr: cb3ab000 ptr: cb3ab008
<hello
>
  test_write: 6
~$

You could also try changing the calls to my_copy_{to,from}_user2()
to my_copy_..._user1() and see if it makes a difference.

Thanks,
Miklos
