Hi,
I've started to iterate on the batch mode discard implementation for reiser4,
and the first question is -- where to place the ioctl handler?
From what I've been able to understand, we need something like
reiser4_ioctl_dir_common() in plugin/file_ops.c, pointer to which should
become ->{unlocked,compat}_ioctl() of directory_f_ops in plugin/object.c.
However, in this case, what is DIRECTORY_FILE_PLUGIN_ID and corresponding
entry in file_plugins array in plugin/object.c? How is it related to
directories?
I see that its ->{inode,file,as}_ops are empty, so it probably does not
participate in dispatching ioctls, but I'd like to make sure this is the case.
Thanks,
