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/prandom.h | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 c_src/include/linux/prandom.h (limited to 'c_src/include/linux/prandom.h') diff --git a/c_src/include/linux/prandom.h b/c_src/include/linux/prandom.h new file mode 100644 index 00000000..9aea22dc --- /dev/null +++ b/c_src/include/linux/prandom.h @@ -0,0 +1,33 @@ +#ifndef _LINUX_PRANDOM_H +#define _LINUX_PRANDOM_H + +#include + +static inline void prandom_bytes(void *buf, int nbytes) +{ + return get_random_bytes(buf, nbytes); +} + +#define prandom_type(type) \ +static inline type prandom_##type(void) \ +{ \ + type v; \ + \ + prandom_bytes(&v, sizeof(v)); \ + return v; \ +} + +prandom_type(int); +prandom_type(long); +prandom_type(u32); +prandom_type(u64); +#undef prandom_type + +static inline u32 prandom_u32_max(u32 max) +{ + return prandom_u32() % max; + +} + +#endif /* _LINUX_PRANDOM_H */ + -- cgit v1.2.3
