Peng Tao c8a3292d24 pnfs/filelayout: fix race between mark_request_commit and scan_commit_lists ... We need to hold cinfo lock while setting bucket->wlseg and adding req to nwritten list at the same time. Otherwise there might be a window where nwritten list is empty yet we set bucket->wlseg, in which case ff_layout_scan_ds_commit_list() may end up clearing bucket->wlseg incorrectly, casuing client to oops later on. This was found when testing flexfile layout but filelayout has the same problem.
