When building for x86-32 (ie make allnoconfig, enable BLOCK, enable BCACHEFS):

../fs/bcachefs/util.h:40: warning: "memcpy" redefined
   40 | #define memcpy(dst, src, len)      \
../arch/x86/include/asm/string_32.h:182: note: this is the location of the previous definition
  182 | #define memcpy(t, f, n) __builtin_memcpy(t, f, n)

In function ‘journal_seq_copy’,
    inlined from ‘__bch2_create’ at ../fs/bcachefs/fs.c:291:3:
../arch/x86/include/asm/cmpxchg.h:128:3: error: call to ‘__cmpxchg_wrong_size’ declared with attribute error: Bad argument size for cmpxchg
which comes from:
../fs/bcachefs/fs.c:52:16: note: in expansion of macro ‘cmpxchg’
   52 |  } while ((v = cmpxchg(&dst->ei_journal_seq, old, journal_seq)) != old);

... and similar problems elsewhere in fs.c.
