glusterfs.git/tests/basic/gfapi/bug-1241104.sh, branch v3.7.19 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. locks: Handle negative values for flock->l_len 2016-02-28T20:14:14+00:00 Soumya Koduri skoduri@redhat.com 2015-07-10T07:10:24+00:00 7e65e1b5a9a7bdaa7ca28bc5c1773bc5472f19af As per 'man 3 fcntl', "If l_len is positive, the area affected shall start at l_start and end at l_start+l_len−1. If l_len is negative, the area affected shall start at l_start+l_len and end at l_start−1. Locks may start and extend beyond the current end of a file, but shall not extend before the beginning of the file." Currently we return EINVAL if l_len is found to be negative.
