2024-12-07kernel: vcache: Add impl of "local" vcachesIan Moffett
This commit implements local vcaches and lazy vcache migration (LZVM) for on the fly vcache type switching. Signed-off-by: Ian Moffett <ian@osmora.org>
2024-12-07kernel: vcache: Improve vcache add/pull interfaceIan Moffett
Require internal add/pull routines to be passed a pointer to the vcache to be operated on. This makes it easier to support for per-process vcaches and LZVM. Signed-off-by: Ian Moffett <ian@osmora.org>
2024-11-13kernel: vfs: Recycle vnodes before allocatingIan Moffett
This commit makes changes to how vnodes are allocated and released. When we want to allocate a new vnode, we check if there is something we can recycle before calling dynalloc(). Instead of calling dynfree() on a vnode, enter it into the vnode cache. 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>
