From: Ira Weiny <ira.weiny@intel.com>

To get to a point of developing and testing the new Lease semantics for long
term file pins[1], add a simple lease test.

Currently the following tests are performed based on the fcntl() man page.

    /*  1 */"Take Read Lease",
    /*  2 */"Take Write Lease",
    /*  3 */"Fail Write Lease if file is open somewhere else",
    /*  4 */"Fail Read Lease if opened with write permissions",
    /*  5 */"Read lease gets SIGIO on write open",
    /*  6 */"Write lease gets SIGIO on read open",

From: Ira Weiny <ira.weiny@intel.com>

locktest uses a pattern which is suitable for lease testing so this
patch copies locktest as a framework and modifies it for lease testing.

Initial tests are built based on the existing fcntl() man page declared
functionality.

Hi Ira,

Can you co-ordinate with Jeff on this? He just posted a patch
to add F_SETLEASE testing with a new binary a few days
ago...

https://marc.info/?l=fstests&m=156690934513424&w=2

Cheers,

Dave.

Sure.

Jeff,

Looking at your submission revealed I was missing 2 tests (shown in the diff
below).

Would it be sufficient to add these to this submission and go with my series?
Or would you prefer using fork vs the socket harness?

I think we may need a fork in the server side of my tests to work on duplicated
FD's but right now I have more tests than you.

Let me know, Thanks,
Ira

    src/leasetest: Add tests to match competing test
    
    A competing patch to test leases was submitted in parallel.[1]
    
    This adds tests which were covered in that patch set.
