By default, rustc passes -nodefaultlibs to the linker. In some cases,
this can cause compiler builtins (e.g. __cpu_model, used by
__builtin_cpu_supports) not to be linked in:
= note: /nix/store/s2cjhni3s6shh0n35ay1hpj8d85k44qk-x86_64-unknown-linux-musl-binutils-2.43.1/bin/x86_64-unknown-linux-musl-ld: ./libbcachefs.a(tools-util.o): in function `resolve_crc32c':
/build/source/c_src/tools-util.c:457:(.text+0x1023): undefined reference to `__cpu_model'
collect2: error: ld returned 1 exit status
I saw this with static musl GCC builds, and others have reported it with
Clang.

Userspace tools and docs for bcachefs
Bcachefs is an advanced new filesystem for Linux, with an emphasis on reliability and robustness and the complete set of features one would expect from a modern filesystem.
This repo primarily consists of the following:
- bcachefs tool, the reason this repo exists.
- {mkfs,mount,fsck}.bcachefs utils, which is just wrappers calling the corresponding subcommands in the main tool
- docs in the form of man-pages and a user manual
Please refer to the main site for getting started An in-depth user manual is (also) found on the official website
Version semantics
The tools relies on an expected disk format structure which is reflected by your current kernel version. Disk format can be upgraded or downgraded automatically by the kernel, if needed.
- Any patch-level change means no disk format change
- Any minor-level change means a potential disk format change which is not breaking
- Any major-level change means breaking changes
