2023-04-27chore(rust): add opt_get! and expose some FMODE_* as Rust constTruongSinh Tran-Nguyen
In an effort to rewrite `bch2_read_super` from C to Rust, it is neccessary to have `opt_get!` macro defined, and some FMODE_* consts (defined as macro in `include/linux/blkdev.h`) defined as Rust const. Bindgen is currently unable to exapnd C functional macro [1], this this commit use the workaround as introduced in [2].

2023-04-26feat(cmd_mount): Add support for magic keyword `OLD_BLKID_UUID`TruongSinh Tran-Nguyen
This commit enhances mount sub command by allowing it to accept `OLD_BLKID_UUID=xxx` as the device, enabling whole fs mounting without relying on colon-separated devices. Using colon-separated devices in fstab is discouraged due to potential device reference issues after reboot. Additionally, using `UUID=xxx` in fstab or with `mount -t bcachefs` is currently infeasible as it depends on blkid, which prior to v2.39, does not recognize bcachefs. This update enables mounting via fstab using `OLD_BLKID_UUID=xxx` as obtained from `bcachefs show-super` "External UUID". Signed-off-by: TruongSinh Tran-Nguyen <i@truongsinh.pro>
2023-04-26chore: logger for idiomatic style and expanded logging levelsTruongSinh Tran-Nguyen
Improve the Rust logger by adhering to idiomatic Rust conventions and incorporating additional logging levels: warn, debug, and trace. Signed-off-by: TruongSinh Tran-Nguyen <i@truongsinh.pro>

2023-02-28rust: Filesystem options now supportedKent Overstreet
This implements opt_set!(), which works exactly the same as the C version and allows filesystem options to be specified in Rust code. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-02-28rust: BkeySCKent Overstreet
Implement a rust equivalent to bkey_s_c, which uses references with the correct lifetimes: now cmd_list.rs doesn't need unsafe. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-02-27Rust: Start of cmd_list rewriteKent Overstreet
This is a _very_ preliminary rewrite of the cmd_list tool in rust, which is intended to be a testing ground for a safe interface in Rust to the core btree interface. This adds rust wrappers for: bch_fs: provides bch2_fs_open(), bch2_fs_stop btree_trans: provides bch2_trans_init(), bch2_trans_exit() btree_iter: provides peek, peek_and_restart, advance bch_errcode: implements Display (wraps bch2_err_str()) bpos: implements Ord (wraps bpos_cmp()) bkey_s_c: implements Display (wraps bch2_bkey_val_to_text()) and other assorted types.

2023-02-21More rust improvementsKent Overstreet
- passing of arguments from c -> rust code now works correctly - 'bcachefs mount' now handles being passed a device or devices Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-02-21Rust now integrated into bcachefs binaryKent Overstreet
Rust is now required for building the bcachefs tool, and rust code is now fully integrated with the C codebase - meaning it is possible to call back and forth. The mount helper is now a subcommand, 'mount.bcachefs' is now a small shell wrapper that invokes 'bcachefs mount'. This will make it easier to start rewriting other subcommands in rust, and eventually the whole command line interface. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
