Hello,
what is the preferred way to increase the maximum number of locks per file in
2.4.18 (and above :-)? Is this fs-type-dependant? My concern is reiserfs 3.6. I
found out the hard way that there is a max of around 128 currently...
Regards,
Stephan

Are you referring to fcntl locks? If so what are the symptoms of not
being able to get a lock? As far as I am aware, there should be no limit
on the number of locks per file (except memory, of course). There is a
per process limit on the number of file locks, but it is infinite by default.
The file system can place restrictions on file locking, but I am
pretty sure that reiserfs does not.
