Minix filesystem until version 2 has a fixed blocksize of 1024 bytes.
If you try to create a filsystem on a device with a physical sectorsize
larger than 1024 bytes, this resulting minix fs cannot be mounted,
because the physical sectorsize must be smaller than the filesystem
blocksize.
This patch adds a check for this and will refuse to create a filesystem
if the sectorsize is bigger than the blocksize.

Further add a missing call to gettext, and undo an unneeded linewrap.

When fgetfilecon() is failed with -ENODATA, this process does not
exit. However, "oldcontext" is not initialized in this case, so
context_new() will be called with uninitialized "oldcontext" at the
next.
Finally, it makes a segmentation fault, because context_new() have to
refer an incorrect memory region.
The attached patch fixes this matter using matchpathcon(). If we
cannot obtain actual file context due to -ENODATA, a context which is
returned by matchpathcon() is applied as oldcontext. Then, the type
of the context is relabeled to "swapfile_t" explicitly.

Let mkswap, mkfs.bfs, mkfs.minix open with O_EXCL if
used on block devices to prevent writing to the device
even if they are busy (mounted).
Unfortunately, O_EXCL has zero effect for 2.4 kernels where
in-kernel code doesn't use O_EXCL-like access locks. (Tested
on RHEL3.)

mkswap(8) enforces to use v0 swap format when pagesize > 16kB.
(use case might be ppc64 with CONFIG_PPC_64K_PAGES).
As version 0 swap is not supported anymore by recent kernels, the
behaviour in this case is rather strange.
Here is a testcase:

In Linux 2.6 the BLKRASET ioctl has the desired effect for mounted
file-systems. In Linux 2.4 it appears to set the number of blocks to
read-ahead on the *device* as opposed to within a *file*, and the
maximum value of this number is 255. As a result the invocation of
blockdev will fail on Linux 2.4 for any usefully large value of
READAHEAD, and will not in any case have the desired affect for
fragmented files.
(Based on the blockdev-getfra-setfra.patch Debian patch.)
