From f5baaf48e3e82b1caf9f5cd1207d4d6feba3a2e5 Mon Sep 17 00:00:00 2001 From: Thomas Bertschinger Date: Mon, 15 Jan 2024 23:41:02 -0700 Subject: move Rust sources to top level, C sources into c_src This moves the Rust sources out of rust_src/ and into the top level. Running the bcachefs executable out of the development tree is now: $ ./target/release/bcachefs command or $ cargo run --profile release -- command instead of "./bcachefs command". Building and installing is still: $ make && make install Signed-off-by: Thomas Bertschinger Signed-off-by: Kent Overstreet --- c_src/include/linux/page.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 c_src/include/linux/page.h (limited to 'c_src/include/linux/page.h') diff --git a/c_src/include/linux/page.h b/c_src/include/linux/page.h new file mode 100644 index 00000000..111e5e68 --- /dev/null +++ b/c_src/include/linux/page.h @@ -0,0 +1,38 @@ +#ifndef _LINUX_PAGE_H +#define _LINUX_PAGE_H + +#include + +struct page; + +#ifndef PAGE_SIZE + +#define PAGE_SIZE 4096UL +#define PAGE_MASK (~(PAGE_SIZE - 1)) + +#endif + +#ifndef PAGE_SHIFT +#define PAGE_SHIFT 12 +#endif + + +#define virt_to_page(p) \ + ((struct page *) (((unsigned long) (p)) & PAGE_MASK)) +#define offset_in_page(p) ((unsigned long) (p) & ~PAGE_MASK) + +#define page_address(p) ((void *) (p)) + +#define kmap_atomic(page) page_address(page) +#define kunmap_atomic(addr) do {} while (0) + +#define kmap_local_page(page) page_address(page) +#define kunmap_local(addr) do {} while (0) + +#define PageHighMem(page) false + +static const char zero_page[PAGE_SIZE]; + +#define ZERO_PAGE(o) ((struct page *) &zero_page[0]) + +#endif /* _LINUX_PAGE_H */ -- cgit v1.2.3
