[LTP] stable-rc: 5.4 and 5.10: fanotify01.c:339: TFAIL: fanotify_mark(fd_notify, 0x00000001, 0x00000008, -100, ".") expected EXDEV: ENODEV (19)

[Naresh Kamboju]

Regression in the LTP syscalls/fanotify01 test on the Linux stable-rc 5.4
and 5.10 kernel after upgrading to LTP version 20250530.

 - The test passed with LTP version 20250130
 - The test fails with LTP version 20250530

Regressions found on stable-rc 5.4 and 5.10 LTP syscalls fanotify01.c
fanotify_mark expected EXDEV: ENODEV (19)

Regression Analysis:
 - New regression? Yes
 - Reproducibility? Yes

Test regression: stable-rc 5.4 and 5.10

Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

fanotify01.c:339: TFAIL: fanotify_mark(fd_notify, 0x00000001,
0x00000008, -100, ".") expected EXDEV: ENODEV (19)

The test expected fanotify_mark() to fail with EXDEV, but received
ENODEV instead. This indicates a potential mismatch between updated
LTP test expectations and the behavior of the 5.4 kernel’s fanotify
implementation.
