[PATCH RESEND 3/3] NFS: Fix commit policy for non-blocking calls to nfs_write_inode()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that the writes will schedule a commit on their own, we don't
need nfs_write_inode() to schedule one if there are outstanding
writes, and we're being called in non-blocking mode.
