timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

 "Bugfixes:

   - Three fixes for looping in the NFSv4 state manager delegation code

   - Fix for the NFSv4 state XDR code (Neil Brown)

   - Fix a leaked reference in nfs_lock_and_join_requests()

   - Fix a use-after-free in the delegation return code

  Features:

   - Implement the NFSv4.2 copy offload OFFLOAD_STATUS operation to
     allow monitoring of an in-progress copy

   - Add a mount option to force NFSv3/NFSv4 to use READDIRPLUS in a
     getdents() call

   - SUNRPC now allows some basic management of an existing RPC client's
     connections using sysfs

   - Improvements to the automated teardown of a NFS client when the
     container it was initiated from gets killed

   - Improvements to prevent tasks from getting stuck in a killable wait
     state after calling exit_signals()"

Pull nfsd updates from Chuck Lever:
 "Neil Brown contributed more scalability improvements to NFSD's open
  file cache, and Jeff Layton contributed a menagerie of repairs to
  NFSD's NFSv4 callback / backchannel implementation.

  Mike Snitzer contributed a change to NFS re-export support that
  disables support for file locking on a re-exported NFSv4 mount. This
  is because NFSv4 state recovery is currently difficult if not
  impossible for re-exported NFS mounts. The change aims to prevent data
  integrity exposures after the re-export server crashes.

  Work continues on the evolving NFSD netlink administrative API.

  Many thanks to the contributors, reviewers, testers, and bug reporters
  who participated during the v6.15 development cycle"

not allow it to do killable waits.

Pull sysctl updates from Joel Granados:

 - Move vm_table members out of kernel/sysctl.c

   All vm_table array members have moved to their respective subsystems
   leading to the removal of vm_table from kernel/sysctl.c. This
   increases modularity by placing the ctl_tables closer to where they
   are actually used and at the same time reducing the chances of merge
   conflicts in kernel/sysctl.c.

 - ctl_table range fixes

   Replace the proc_handler function that checks variable ranges in
   coredump_sysctls and vdso_table with the one that actually uses the
   extra{1,2} pointers as min/max values. This tightens the range of the
   values that users can pass into the kernel effectively preventing
   {under,over}flows.

 - Misc fixes

   Correct grammar errors and typos in test messages. Update sysctl
   files in MAINTAINERS. Constified and removed array size in
   declaration for alignment_tbl

If we already had a valid port number for the RPC service, then we
should not allow the rpcbind client to set it to the invalid value '0'.

Propagate the NFS_MOUNT_NETUNREACH_FATAL flag to work with the generic
NFS client. If the flag is set, the client will receive ENETDOWN and
ENETUNREACH errors from the RPC layer, and is expected to treat them as
being fatal.
