ext4 was corrupting inode table bitmaps due to a mishmash of
atomic & nonatomic bitops. This got broken twice and fixed
twice; let's add a test.
On a 4-way box this reliably ends up with a corrupted filesystem
if we get it wrong (upstream as of 2.6.35 at least is fine again)

NIS detection wasn't tested on machines without NIS enabled, so many tests are
failing on non-NIS machines. the _yp_active function has no specific return
value so always evaluates as 0 (active) and the "_cat_passwd" function is
called from within an awk script which is not valid as the shell may run with a
sanitised environment. Hence the functions do not need specific export calls,
either, as unsanitised subshells will automatically inherit the parent's
environment.

There's no need to re-make the dependency files all the time. Make
it so the "depend" target rebuilds the ".dep" file only if necessary.
Also change the name of the dependency file created for "ltdepend"

This patch arranges for calls to getfacl(1) to be given the "-n"
flag, which requests that user and group id's be listed numerically
rather than using names. The affected test output files are also
updated to indicate the effect of the change.
This eliminates some spurious output differences I was seeing, due
to the presence of NIS in my test environment.

If NIS is active on a test target system, additional password and
group file information is available via their respective databases
in NIS. Currently, some tests assume that /etc/passwd and /etc/group
are the only places to find this information.
This patch causes both the local database and the NIS database (if
one is likely to be present) to be consulted for needed information.

This replicates file corruption we've seen with qemu-kvm when
we use if=virtio,cache=none,aio=native for IO to a sparse
ext4- or xfs-hosted file, and the partitions/filesystems
within that file image are not block-aligned. (think sector
63 here...) This results in AIO IOs not aligned to the
filesystem blocks.
This test modifies aiodio_sparse2.c to add an option to start
the file IO at an offset.
When we do 4k writes to a 16k file in 2 threads, starting
at offset 512, we get 0s interspersed in the file where they
should not be:

Test 214 and 236 use the same file names for test files in the TEST

you run 214 then 236, 236 will fail with:

+ctime: 1277076527 -> 1277076527

ensure a clean state before they start.

When Christoph and I were discussing bulkstat coherency on IRC, we
realised that inode lookup from bulkstat was not actually looking up
the inode allocation btree in xfs_imap() before reading the inode
buffer from disk in xfs_iread(). Bulkstat uses the same lookup
mechanism as handle validation to avoid shutting down the filesystem
if inode numbers that point to non-inode buffers (i.e. invalid) are
passed in the handle.
The problem with this is that when we delete inodes from disk and we
remove the inode chunk (i.e. deallocate inodes) we mark both the
inodes in memory and the cluster buffer as stale, thereby preventing
it from being written back to disk. The result of this is that some
number of inodes remain on disk looking like allocated, in use
inodes (i.e. di_mode is not zero).
Hence if we get a cold cache lookup from a stale handle that
references such an inode, we can read the inode off disk even though
it has been deleted because we don't check if the inode is allocated
or not. If the inode chunk has not been overwritten, then the inode
read will succeed and the handle-to-dentry conversion will not error
out like it is supposed to. The result is that stale NFS filehandles
and open_by_handle() will succeed incorrectly on unlinked files for
cold cache lookups.
This is a bug that has been present ever since the inode chunk
deletion code was implemented. This test exercises the problem and
documents the hoops you have to jump through to reproduce it.

By default xfs_io uses a buffer size of 4096 bytes. On test 226,
the result is that the test runs much slower (at least an order
of magnitude) than it needs to.
Add a flag to the "pwrite" command sent to xfs_io so it uses
larger buffers, thereby speeding things up considerably.

The test for fallocate was broken because it used $TEST_DIR/$tmp.io. Because
$tmp is usually something like /tmp/1234 or /mnt/1234 the file cannot be
created and xfs_io fails regardless of existance of fallocate support. Moreover
the subsequent message parsing decides that fallocate is actually supported
because it does not expect this message.
Fix the test to not use $tmp.

For all 2.6 kernels presence of quota support in kernel can be detected by
checking /proc/sys/fs/quota. This is actually more reliable than trying to
mount a filesystem with quota options (for example because SCRATCH_DEV does
not have to contain a filesystem type we are going to test).
