2024-05-09f2fs: remove unused GC_FAILURE_PINChao Yu
After commit 3db1de0e582c ("f2fs: change the current atomic write way"), we removed all GC_FAILURE_ATOMIC usage, let's change i_gc_failures[] array to i_pin_failure for cleanup. Meanwhile, let's define i_current_depth and i_gc_failures as union variable due to they won't be valid at the same time.

2024-05-09erofs: Zstandard compression supportGao Xiang
Add Zstandard compression as the 4th supported algorithm since it becomes more popular now and some end users have asked this for quite a while [1][2]. Each EROFS physical cluster contains only one valid standard Zstandard frame as described in [3] so that decompression can be performed on a per-pcluster basis independently. Currently, it just leverages multi-call stream decompression APIs with internal sliding window buffers. One-shot or bufferless decompression could be implemented later for even better performance if needed.

Commit 809216233555 ("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler.

2024-05-08selftests/resctrl: fix clang build warnings related to abs(), labs() callsJohn Hubbard
When building with clang, via: make LLVM=1 -C tools/testing/selftests ...two types of warnings occur: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value warning: taking the absolute value of unsigned type 'unsigned long' has no effect Fix these by: a) using labs() in place of abs(), when long integers are involved, and b) Change to use signed integer data types, in places where subtraction is used (and could end up with negative values). c) Remove a duplicate abs() call in cmt_test.c.

2024-05-08bpf: Avoid uninitialized value in BPF_CORE_READ_BITFIELDJose E. Marchesi
[Changes from V1: - Use a default branch in the switch statement to initialize `val'.] GCC warns that `val' may be used uninitialized in the BPF_CRE_READ_BITFIELD macro, defined in bpf_core_read.h as: [...] unsigned long long val; \ [...] \ switch (__CORE_RELO(s, field, BYTE_SIZE)) { \ case 1: val = *(const unsigned char *)p; break; \ case 2: val = *(const unsigned short *)p; break; \ case 4: val = *(const unsigned int *)p; break; \ case 8: val = *(const unsigned long long *)p; break; \ } \ [...] val; \ } \ This patch adds a default entry in the switch statement that sets `val' to zero in order to avoid the warning, and random values to be used in case __builtin_preserve_field_info returns unexpected values for BPF_FIELD_BYTE_SIZE. Tested in bpf-next master. No regressions. Signed-off-by: Jose E.

2024-05-08bcachefs: Move BCACHEFS_STATFS_MAGIC value to UAPI magic.hPetr Vorel
Move BCACHEFS_STATFS_MAGIC value to UAPI <linux/magic.h> under BCACHEFS_SUPER_MAGIC definition (use common approach for name) and reuse the definition in bcachefs_format.h BCACHEFS_STATFS_MAGIC. There are other bcachefs magic definitions: BCACHE_MAGIC, BCHFS_MAGIC, which use UUID_INIT() and are used only in libbcachefs. Therefore move only BCACHEFS_STATFS_MAGIC value, which can be used outside of libbcachefs for f_type field in struct statfs in statfs() or fstatfs().

2024-05-08bcachefs: Allocator prefers not to expand mi.btree_allocated bitmapKent Overstreet
We now have a small bitmap in the member info section of the superblock for "regions that have btree nodes", so that if we ever have to scan for btree nodes in repair we don't have to scan the whole device(s).
