Bootloader fork rebase:
- Base changed from 0.1.0 pre-patched archive to upstream 1.0.0 tag (c7eeb9f)
- Applied 0001-redbear-local-forks.patch (Cargo.toml crate path redirects)
- Applied fix-uefi-alloc-panic.patch equivalents (4 panic!() -> graceful
error handling in src/main.rs)
- Applied P5-live-preload-cap-1gib.patch (1 GiB cap on live image preload)
- Skipped: P0 GPT partition scan (requires new module + integration),
P1 timeout/default-resolution, P2 live preload guard (subsumed by
panic fixes + cap), P3 live image safe read, P4 large ISO boot,
redox.patch — to be applied in dedicated rebase session.
firmware-loader/Cargo.toml: version 0.1.0 -> 0.3.0 (sync with other
Red Bear custom crates which are at 0.3.0).
fork-upstream-map.toml: bootloader back from PENDING_REBASE to 1.0.0
since the partial rebase matches upstream 1.0.0 content.
fork-upstream-map.toml: base restored to 'main' tracked (was correctly
tracked by build-redbear.sh).

/* Use "ignore_value" to avoid a warning when using a function declared with
|
|
gcc's warn_unused_result attribute, but for which you really do want to
|
|
ignore the result. Traditionally, people have used a "(void)" cast to
|
|
indicate that a function's return value is deliberately unused. However,
|
|
if the function is declared with __attribute__((warn_unused_result)),
|
|
gcc issues a warning even with the cast.
|
|
|
|
Caution: most of the time, you really should heed gcc's warning, and
|
|
check the return value. However, in those exceptional cases in which
|
|
you're sure you know what you're doing, use this function.
|
|
|
|
For the record, here's one of the ignorable warnings:
|
|
"copy.c:233: warning: ignoring return value of 'fchown',
|
|
declared with attribute warn_unused_result". */
