1) _require_fiemap and _require_xfs_io_command "fiemap" do the
same thing, but some test cases use the former and some use
the latter, so i feel they should be unified.
2) The number of helpers like this is slowly growing, but it's
easy to simply use _require_xfs_io_command directly and just
specify the command we want to check.
This is just a cleanup for keeping it simple.

Currently hardlinks do not preserve the inode number across copy up,
so hardlinks did not participate in this test so far.
Stay honest and let the test verify what is was meant to verify and
let it fail because of the fact that hardlinks inode numbers are not
constant across copy up.

'find -ino' is this test was supposed to filter files by inode
number that was recorded with 'ls -i' to compare st_ino returned by
stat(2) with d_ino returned by getdents64(2).
It turns out that on some systems, 'find -ino' uses stat(2) for
filtering by inode number, which is not what we want.
Use the auxiliary program t_dir_type to filter files by inode number
instead.

Bash's 'type -P' builtin is equivalent to 'which', but it's more
efficient because it doesn't involve executing an external binary.
Because set_prog_path() is executed 60+ times in common/config,
which is sourced by common/rc, which in turn is sourced by every
test, switching to 'type -P' actually can make a noticeable
performance improvement for short-running or skipped tests. For
example:
Before:
# time ./check generic/002
...
Passed all 1 tests
real 0m1.365s
user 0m0.746s
sys 0m0.644s
After:
# time ./check generic/002

Add a test which verifies that dentries in an encrypted directory
are invalidated when an encryption key is added --- which should
cause the plaintext filenames to be visible and accessible,
replacing the encoded ciphertext filenames and any negative dentries
for the plaintext names. This primarily tests for a bug which was
fixed in the v4.5 kernel, plus a v4.6 fix for incorrect RCU usage in
the earlier fix.

path isn't an active xfs mountpoint, the command is rejected. The
purpose is to check the command response, but not necessarily the
functionality of xfs_growfs. Test cases include absolute paths,

This adds a regression test for the following kernel patch:
dax: fix data corruption due to stale mmap reads
The above patch fixes an issue where users of DAX can suffer data
corruption from stale mmap reads via the following sequence:
- open an mmap over a 2MiB hole
- read from a 2MiB hole, faulting in a 2MiB zero page
- write to the hole with write(3p). The write succeeds but we incorrectly
leave the 2MiB zero page mapping intact.
- via the mmap, read the data that was just written. Since the zero page
mapping is still intact we read back zeroes instead of the new data.
