Hello all.
The following issue has been found with posix_fadvise:
the system call succeeds on a pipe or FIFO, although it has to fail with 
EINVAL return value on linux.
I've attached a small test for posix_fadvise and a patch for linux 
kernel 2.6.14 that fixes the problem.
The patch makes posix_fadvise return ESPIPE on FIFO/pipe in order to be 
fully POSIX-compliant.
Please, take a look at these. Is it really a bug in kernel?
Thanks.
