Make the large_file_test check if there is at least 3GB of free disk
space and skip the test if there is not. This is to make the tests pass
on a VM with limited disk size, now all functional tests are passing.

Without it incfs/incfs_perf runtime fails in format_signature:
malloc(): invalid size (unsorted)
Aborted
When compiled with gcc version 11.2.0.
Also add check for NULL after the malloc, and remove unneeded
space for uint32_t in signing_section.

For incfs files that were created without a merkle tree, enabling verity
requires building a merkle tree first. Although this is the same logic
as verity performs, it is not that easy to reconcile the two given that
incfs has the merkle tree potentially when verity is not enabled.

Now fsverity state is preserved across inode eviction.

This does not (yet) preserve the verity status once the inode is

Test failure was caused by drop_caches sometimes not dropping a range of
sectors in the middle of a random file. Fix by changing to reading the
file before we populate it, so the cache is not involved. Also by
populating it only on the last test, we test logging on both populated
and unpopulated files.
Rewrite the tests with the new test macros, and make the whole test far
more readable.
Test was taking 100 seconds to run, which was half the total runtime for
all the tests. This was due to the sleeps while reading. Reduce number
of such sleeps by a factor of 10, halving total test runtime.
Also incfs_test would exit with 0 whether tests failed or not. Fix.

Also fixed two bugs in the process:
is_pseudo_filename was not previously checking for .log, so an attempt
to create a .log would succeed.
All ioctls could be called on all files. ioctls now set on the correct

The binderfs test mixed the full harness API and the selftest API.
Adjust to use only the harness API so that the harness API can switch
to using the selftest API internally in future patches.

This test case catches lost wake up introduced by commit 339ddb53d3
("fs/epoll: remove unnecessary wakeups of nested epoll")
The test is simple: we have 10 threads and 10 event fds. Each thread
can harvest only 1 event. 1 producer fires all 10 events at once and
waits that all 10 events will be observed by 10 threads.
In case of lost wakeup epoll_wait() will timeout and 0 will be returned.
Test case catches two sort of problems: forgotten wakeup on event, which
hits the ->ovflist list, this problem was fixed by:
5a2513239750 ("eventpoll: fix missing wakeup for ovflist in ep_poll_callback")
the other problem is when several sequential events hit the same waiting
thread, thus other waiters get no wakeups. Problem is fixed in the
following patch.
