J. Bruce Fields f9d7562fdb nfsd4: share file descriptors between stateid's ... The vfs doesn't really allow us to "upgrade" a file descriptor from read-only to read-write, and our attempt to do so in nfs4_upgrade_open is ugly and incomplete. Move to a different scheme where we keep multiple opens, shared between open stateid's, in the nfs4_file struct. Each file will be opened at most 3 times (for read, write, and read-write), and those opens will be shared between all clients and openers. On upgrade we will do another open if necessary instead of attempting to upgrade an existing open. We keep count of the number of readers and writers so we know when to close the shared files.
