Fix to avoid deadlock in _libgf_umount by using _libgf_vmp_search_entry instead of libgf_vmp_search_exact_entry since the latter tries to take a lock already help by _libgf_umount. 2.

At that time, we did not have a solution to the problem of when to init the vmplist in a thread-safe manner, since there was no lock to protect the vmplock specifically, and that when libgf_vmp_map_ghandle was called inside glusterfs_mount so the "lock" was already being held.

| | | | | | | | | | | | | | | | | | | | | Till now we've been creating an iovec, storing references in it to the application data and simply passing it on to the translator tree. This means that the buffer being passed to the translators is not at all associated with the memory ref'd by the iobref argument to write fop. This is a problem when write-behind is a translator in the tree since it assumes that the memory in the iovecs passed to write fops is already refcounted by the iobref and so it simply copies the address of the application data. The problem is that the application can continue using this buffer, free it or over-write it destroying the data that write-behind may write at a later time. The solution involves copying the application's write buffer into an iobuf which will be referred to by the iobref. Signed-off-by: Anand V.

| | | | | | | | | | | | | 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>
