performance/write-behind: initialize lock in wb-file before wb-file is set in fd-ctx.

2011-05-08T06:03:47+00:00

- Consider a combination of fuse->quick-read->read-ahead->wb->client.
    quick-read can do open-behind (open is returned as success even
    before it is issued to backend) and hence the fd can already be
    in the list of open fds of the inode. A flush call on some other
    fd opened on the same inode, will result in ra_flush issuing flush
    calls to all the fds opened on the same inode. This can result in
    wb_flush trying to hold a lock on non-initialized lock there by causing
    memory corruption.
