3 dayskernel: descrip: Add 'td' parameter to fd routinesIan Moffett
Update the signature of 'fd_get()', 'fd_alloc()' and 'fd_dup()' to include a pointer to the process to target. This improves the flexibility of the file descriptor API. Signed-off-by: Ian Moffett <ian@osmora.org>

2024-11-04kernel: descrip: Add support for fd duplicationIan Moffett
Sometimes we may need to duplicate a file descriptor and create a new fdno that refers to the same vnode. The fd_dup() function enables us to do this when needed. Signed-off-by: Ian Moffett <ian@osmora.org>
