Reviewed-by: Petr Vorel <[email protected]> FYI Cyril Hrubis suggested a different approach (for LTP tests which is based on this Al's test): https://lore.kernel.org/ltp/[email protected]/ https://lore.kernel.org/ltp/[email protected]/ filedescriptor that is >= 64 and set the nr_open to 64. That would help to avoid using /proc/sys/fs/nr_open. Kind regards, Petr > thanks, > -- Shuah
