Bananymous 0af74fccda Kernel/LibC: Rework dirent structure 
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.

Bananymous b7007016c0 BAN: Implement Ext2 file unlinking 
Ext2 inodes can now be unlinked from directories and after last
inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem

Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan

for reading and writing.

Bananymous 3e5645d453 Kernel: Add API for RamDirectoryInodes to delete containing inodes 2023-09-30 19:22:30 +03:00
Bananymous 43c23db4a6 Kernel: Implement MAP_SHARED for regular files 
Every inode holds a weak pointer to shared file data. This contains
physical addresses of pages for inode file data. Physical addresses
are allocated and read on demand.

When last shared mapping is unmapped. The inodes shared data is freed
and written to the inode.

Bananymous 9bcfb34524 Kernel: Rewrite whole device structure
