[LTP] [PATCH v3] inotify13: check rename cookie pairing after adjacent moves

[Hungyu Lin]

Following up on my earlier reply, I'd like to confirm that I've understood
your feedback correctly before sending v4.

Below are example outputs for the seven failure diagnostics.

1. Extra event

    file: got unnecessary event 3: mask=0x40 wd=1 cookie=123 len=16 name="entry"

2. Wrong event mask

    file: got event 1: mask=0x80 (expected 0x40) wd=2 cookie=123 name="entry"

3. Wrong watch descriptor

    file: got event 0: mask=0x40 wd=2 (expected 1) cookie=123 name="entry"

4. Wrong filename

    file: got event 0: mask=0x40 wd=1 cookie=123 len=16 name="other"
(expected "entry")

5. Missing event

    file: didn't get event 2: mask=0x80 wd=2 name="entry"

6. Identical cookies for the two FROM events

    file: got second FROM cookie=123 (expected != 123), wd=1 mask=0x40
name="entry"

7. Mismatched cookies for the second FROM/TO pair

    file: got TO cookie=125 (expected 124 from second FROM), wd=2
mask=0x80 name="entry"

Do these follow the pattern you meant? In particular, would you omit any
of the additional event context, such as wd or cookie in the mask-mismatch
message?

I'd appreciate your feedback before I send v4.

Thanks,
Hungyu
