2021-10-17port virtio_disk to virtio spec 1.0+Xi Wang3-37/+52
The legacy interface is confusing. It's better to make virtio_disk conform to the virtio spec. This is supported in QEMU since 4.2 by disabling force-legacy for virtio-mmio.

The terminating NULL string is already included (see sys_exec()).
2021-08-31Assert that the size in mappages() is always positivel0stman1-1/+4
If va % PGSIZE == 0 and size == 0, we have last < a at the start of the loop so we might never terminate. That being said, this particular case couldn't be triggered for now.

2020-11-23Rename icache to itableFrans Kaashoek1-25/+25
The inode cache isn't really a cache. The main purpose of it is to allow for synchronization (locking individual inodes), providing long-lived references to inodes, and ensuring that there is only inode in memory.
