MFC r331630: Fix instructions in the zfsboot manual page.

2018-04-03T14:09:34+00:00

zfsloader(8) fails to probe a slice containing ZFS pool if its second sector
contains traces of BSD label (DISKMAGIC == 0x82564557).
Fix manual page to show working example erasing such traces.

Fix printf format warning in zfs_module.c

Clang 5.0.0 got better warnings about print format strings using %zd,
and this leads to the following -Werror warning on e.g. arm:

    sys/boot/efi/boot1/zfs_module.c:186:18: error: format specifies type 'ssize_t' (aka 'int') but the argument has type 'off_t' (aka 'long long') [-Werror,-Wformat]
                        "(%lu)\n", st.st_size, spa->spa_name, filepath, EFI_ERROR_CODE(status));
                                   ^~~~~~~~~~

Fix this by casting off_t arguments to intmax_t, and using %jd instead.

Wrap bootcamp DEBUG statement with curly braces

This fixes a -Wempty-body warning with gcc 6.3.0 when PART_DEBUG is undefined.

Tested with:	amd64-gcc-6.3.0 (devel/amd64-xtoolchain-gcc)

r309412 (by imp):

dd is currently a bootstrap tool. It really doesn't have any business
being a bootstrap tool. However, for reproducible build output,
FreeBSD added dd status=none because it was otherwise difficult to
suppress the status information, but retain any errors that might
happen. There's no real reason that dd has to be a build tool, other
than we use status=none unconditional. Remove dd from a bootstrap tool
entirely by only using status=none when available. This may also help
efforts to build the system on non-FreeBSD hosts as well.

r316109:

Don't hardcode input files for stage 1/2 bootloaders; use .ALLSRC instead

This is a better pattern to follow when creating the bootloaders and doing
the relevant space checks to make sure that the sizes aren't exceeded (and
thus, copy-pasting is a bit less error prone).

r316132:

Parameterize out 7680 (15 * 512) as BOOT2SIZE, similar to sys/boot/i386/zfsboot/...

This is being done to make it easier to change in the future--this action might be
needed sooner rather than later because of gcc 6.3.0 bailing, stating that there
is negative free space left (deficit) in the boot2 bootloader.

Don't shadow read(2) definition with `read` argument in vdev_{create,probe}

This fixes several -Wshadow warnings introduced in r192194, but now errors
with gcc 6.3.0.

Remove redundant declaration for `zfs_crc64_table`

zfssubr.c already defines this statically. Besides, zfsimpl.c defined it, but
didn't use it.

This fixes a -Wredundant-decls warning.
