Patch for Linux kernel modifying read/write family syscalls to allow buffering file changes before committing. This was an Advanced Topics in Operating Systems assignment #2 in 2020 at MIMUW faculty.

The patch for kernel 5.5.5 is contained in wb-linux-5.5.5.patch. The solution does not modify mmap, sendfile and some other syscalls. The commit is not atomic. It works with (p)read(v)/(p)write(v) family.
