[LTP] [PATCH] fctnl23: can't set a read lease on a r/w open file

[Roman K. <rk...@sw...>]

  Hi,

Test testcases/kernel/syscalls/fcntl/fcntl23.c fails (at least on
2.6.8+ kernels) with fcntl(fd, F_SETLEASE,F_RDLCK) resulting in EAGAIN.

AFAICT the reason is that it attempts to set a read lease on a file
which it opens read/write.

The attached file fixes it to open the file readonly.

Please consider applying.

Roman.
