LU-7473 acl: increase ACL entries limitation

Originally, the limitation of ACL entries is 32, that is not
enough for some use cases. In fact, restricting ACL entries
count is mainly for preparing the RPC reply buffer to receive
the ACL data. So we cannot make the ACL entries count to be
unlimited. But we can enlarge the RPC reply buffer to hold
more ACL entries. On the other hand, MDT backend filesystem
has its own EA size limitation. For example, for ldiskfs case,
if large EA enable, then the max ACL size is 1048492 bytes;
otherwise, it is 4012 bytes. For ZFS backend, such value is
32768 bytes. With such hard limitation, we can calculate how
many ACL entries we can have at most. This patch increases
the RPC reply buffer to match such hard limitation. For old
client, to avoid buffer overflow because of large ACL data
(more than 32 ACL entries), the MDT will forbid the old client
to access the file with large ACL data. As for how to know
whether it is old client or new, a new connection flag
OBD_CONNECT_LARGE_ACL is used for that.

LU-8294 gss: quiet cache_check return ENOENT warning

gss_svc_upcall_handle_init spews a lot of error messages if GSS
support has been compiled, but GSS is not being used. The current
error message is not very useful, so this patch moves it to CDEBUG.

LU-9439 scripts: Change behavior of lustre_rmmod

The lustre_rmmod script was modified to take an arbitrary list of
modules and try to remove them and any modules dependent on them.
Previously its behavior was to always remove the libcfs module,
along with either the ldiskfs or another module passed as a
parameter.

The old interface was roughly maintained. Any of the following
commands will remove the ldiskfs, libcfs, and all dependent modules:

    $ lustre_rmmod
    $ lustre_rmmod ldiskfs
    $ lustre_rmmod ldiskfs libcfs

The benefit now, is that any other list of modules can be specified
without removing libcfs. For example, the following command will only
remove ptlrpc and its dependent modules (leaving libcfs intact):

    $ lustre_rmmod ptlrpc

The lnet init script was modified to perform a lustre_rmmod ptlrpc
before performing an lctl network down. By removing the ptlrpc
module, we can ensure that lnet is not in use. This will help
systems running lustre to shut down cleanly.

LU-4423 ptlrpc: use 64-bit times for request times

All request timestamps and deadlines in lustre are recorded in time_t
and timeval units, which overflow in 2038 on 32-bit systems.

In this patch, I'm converting them to time64_t and timespec64,
respectively. Unfortunately, this makes a relatively large patch,
but I could not find an obvious way to split it up some more without
breaking atomicity of the change.

Also unfortunately, this introduces two instances of div_u64_rem()
in the request path, which can be slow on 32-bit architectures. This
can probably be avoided by a larger restructuring of the code, but
it is unlikely that lustre is used in performance critical setups
on 32-bit architectures, so it seems better to optimize for correctness
rather than speed here.

REP-ACK, while Commit-on-Sharing doesn't take effect for

1. save local locks upon unlock as before, but don't convert

3. otherwise for uncommitted reply convert locks to COS mode,
   and later when it's committed, ptlrpc_commit_replies()
   wakes up ptlrpc_handle_rs() again, which will decref locks

LU-8307 ldlm: cond_resched in ldlm_bl_thread_main

When clearing all of the ldlm LRUs (as Cray does at the end of
a job), a ldlm_bl_work_item is generated for each namespace
and then they are placed on a list for the ldlm_bl threads to
iterate over.

If the number of namespaces greatly exceeds the number of
ldlm_bl threads, a given thread will iterate over many
namespaces without sleeping looking for work.  This can go
on for an extremely long time and result in an RCU stall.

This patch adds a cond_resched() between completing one
work item and looking for the next.  This is a fairly cheap
operation, as it will only schedule if there is an
interrupt waiting, and it will not be called too much -
Even the largest file systems have < 100 namespaces per
ldlm_bl_thread currently.

LU-8879 tests: speed up copytool_cleanup() in sanity-hsm

This patch implements the following improvements:

 - The coordinator now wakes up when hsm_control is set to 'shutdown'

 - The wait_copytools() function in sanity-hsm uses a polling
   mechanism to detect when all running copytools are killed.
   It used to sleep before the first check, even though that check
   would pass most of the time. This has been fixed.

 - wait_copytools() used to sleep for 2s between its checks. It now
   sleeps for 0.1s, 0.2s, 0.4s, 0.8s, 1.6s, 3.2s, 3.2s, 3.2s, ...
   until it times out.

Considering how often the wait_copytools() function is called in
sanity-hsm, this patch should represent a noticeable speed-up.

LU-8998 llapi: rename llapi_layout_comp_move -> *use

Rename llapi_layout_comp_move() and llapi_layout_comp_move_at()
to llapi_layout_comp_use() and llapi_layout_comp_use_id(),
respectively.  This avoids confusion about what "move" and "at" in
the function name implies. The component itself is not actually
being moved, just a different layout component is being selected
for access or modification.  Using "_id" instead of "_at" also
makes it more clear what the difference is between these functions.

Rename LLAPI_LAYOUT_COMP_POS_{FIRST,NEXT,LAST} correspondingly to
LLAPI_LAYOUT_COMP_USE_{FIRST,NEXT,LAST} to match.

Split llapi_layout_comp_use_id.3 from llapi_layout_comp_use.3 since
they are mostly independent anyway.

LU-3308 mdc: allow setting readdir RPC size parameter

Allow the mdc.*.max_pages_per_rpc tunable to set the MDS bulk
readdir RPC size, rather than always using the default 1MB RPC
size.  The tunable is set in the MDC, as it should be, rather
than in the llite superblock, which requires extra code just to
get it up from the MDC's connect_data only to send it back down.
The RPC size could be tuned independently if different types of
MDSes are used (e.g. local vs. remote).

Remove the md_op_data.op_max_pages and ll_sb_info.ll_md_brw_pages
fields that previously were used to pass the readdir size from
llite to mdc_read_page().  Reorder some 32-bit fields in md_op_data
to avoid struct holes.

Remove lprocfs_obd_rd_max_pages_per_rpc() as it is no longer used.
Move osc_obd_max_pages_per_rpc_seq_write() to obdclass along with
lprocfs_obd_max_pages_per_rpc_seq_show().

Remove debug messages from fid_flatten*() since this clutters up
the debug logs, and is redundant with other debug messages.

Fix test_24v's calculation for the number of RPCs being sent, so
that it will be correct even if the readdir RPC size is modified.
Register cleanup trap to avoid leaving lots of files behind.

Merge "slow" sanity test_24D into test_24v since they both need to
have many files in a single directory, which avoids duplication.

Change calc_osc_stats() and calc_llite_stats() into calc_stats()
to be used in test_24v and other tests.  Similarly, clear_osc_stats()
and clear_llite_stats() are consolidated into clear_stats().

This patch adds two flags to nodemaps which control whether or not
the nodemap should map UIDs, GIDs, or both. These flags can be
controlled via lctl as a new nodemap parameter map_mode, with values
both, uid_only, or gid_only.
