2026-08-28kernel/vfs: implement read_directory fixups.Felix Morgner6-2/+134
POSIX requires that the data returned by the readdir() function shows the inode number of the root of a mounted filesystem for its mount point. Additionally, the inode number of the '..' reference in the mounted filesystem must show the inode number of the mount point. We perform this fixup when computing the entries during read_directory on the fly. The implementation of the upward fixup will need to be revised once the kernel supports bind mounts.

2026-08-28kernel/vfs: implement root swivel and mount moveFelix Morgner9-71/+92
Previously, the device filesystem (devfs) was simply grafted on each root filesystem during boot. This caused the existence of an unreachable, dead devfs mount after the VFS instance had been initialized. This changeset implements the ability to relocate an active mount from one mount point to another. That way, no second devfs mount needs to be created. Instead, the existing devfs mount is relocated to a mount point in the persistent root filesystem that get mounted during initialization. Secondly, this changeset also alters the VFS initialization flow, so that only one root mount exists after initialization finishes.

2026-08-28kernel/fs: ext2: fix block allocation on 1 KiB fsFelix Morgner1-2/+2
When computing the actual block numbers for a filesystem, care must be taken to account for which block is the actual first data block. For 1 KiB block size filesystems, that block is actually block 1, not 0. This is because the first 1 KiB on any ext2 volume is reserved for bootloader data. Complicating matters, the bitmaps don't take this into account. They essentially reflect a logical view, describing which data blocks are already allocated. On a 1 KiB filesystem, this effectively means that bit 0 of the allocation bitmap references physical block 1. Luckily, we don't need to make that determination based on the block size at all. The superblock already carries the number of the first data block. That means one can simply add that number, which is 1 in the 1 KiB block size case and 0 otherwise, to the found block index. Interestingly, this was already caught by accident when locating the authoritative block group descriptor (BGD) table. A factor of two was multiplied into the calculation in the case of a 1 KiB block size. This factor arises because the primary BGD table follows the primary superblock. Since the superblock is located in physical block 0 in all cases except for a 1 KiB block size, the BGD table generally lands in block 1. This implies an offset of 1 block size from the volume start. In the 1 KiB case, the BGD table lands in block number 2, effectively at an offset of 2 blocks from the start of the volume. This changeset makes that calculation explicit in the BGD table locator code as well. This clarifies the previously obscure factor of 2.
