* We have uf_info_t for areleasef(). We implement areleasef() using a global

|
|
* linked list of all open file descriptors with the task structs referenced,
|
||
|
|
* so accessing the correct descriptor from areleasef() only requires knowing
|

|
* about the Linux task_struct. Since this is internal to our compatibility
|
||
|
|
* layer, we make it an opaque type.
|
||
|
|
*
|
||
|
|
* XXX: If the descriptor changes under us and we do not do a getf() between
|
||
|
|
* the change and using it, we would get an incorrect reference.
