[Gluster-devel] Is lock (fcntl) supported by multilple concurent client ?

[Anand Avati]

Hi!
you need to use fuse.ko from fuse-2.6.x from fuse.sf.net.
the standard kernels' fuse dont support locking as the 2.6 fuse is not
yet merged into mainstream kernel.

Also locking code is undergoing some changes so please keep using the
tla checkout rather than the tarball.

regards,
avati
