Trond Myklebust	05990d1bf2	NFS: Fix fdatasync/fsync() when confronted with a server reboot ... If the server reboots before it can commit the unstable writes to disk, then nfs_commit_release_pages() will detect this when it compares the verifier returned by COMMIT to the one returned by WRITE. When this happens, the client needs to resend those writes in order to guarantee that they make it to stable storage. This patch adds a signalling mechanism to notify fsync() that it needs to retry all writes before it can exit. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>	2012-09-28 16:03:05 -04:00
Trond Myklebust	7b281ee026	NFS: fsync() must exit with an error if page writeback failed ... We need to ensure that if the call to filemap_write_and_wait_range() fails, then we report that error back to the application.
