glusterfs.git/libglusterfsclient/src, branch v2.0.3 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. libglusterfsclient: Use O_ACCMODE for access mode checks 2009-07-02T17:14:48+00:00 Shehjar Tikoo shehjart@gluster.com 2009-07-02T00:52:28+00:00 cf87dfa3f44172635b9d071c83cd2fcd2479c668 Ref: http://www.gnu.org/s/libc/manual/html_node/Access-Modes.html Signed-off-by: Anand V.

libglusterfsclient: Fix glusterfs_mount-vmp search deadlock 2009-06-30T22:24:53+00:00 Shehjar Tikoo shehjart@gluster.com 2009-06-26T13:05:00+00:00 e4a4d04a691a27c1e52e8e0f78458fb4ebf00912 It is possible that the only translator in the libglusterfsclient tree is the posix. In that case, inside gluster_init, the graph init routines will need to call lstat on the posix subdirectory. Since even the glusterfs stack is running over booster, those calls will also first require vmp searching. BUT, the vmp lock is the same as the mount lock that was already taken when we entered glusterfs_mount, so a deadlock occurs. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> 
It is possible that the only translator in the libglusterfsclient
tree is the posix. In that case, inside gluster_init, the graph
init routines will need to call lstat on the posix subdirectory.

Since even the glusterfs stack is running over booster, those
calls will also first require vmp searching. BUT, the vmp lock
is the same as the mount lock that was already taken when we entered
glusterfs_mount, so a deadlock occurs.
