LU-14729 osd-ldiskfs: fix to declare write commits

Fallocation might introduce unwritten extents, writting
data will trigger extents split, so we should reserve
credits for this case, to avoid complicated calculation,
we just use normal credits calculation if extent is mapped
as unwritten.

See comments in ext4:
If we add a single extent, then in the worse case, each tree
level index/leaf need to be changed in case of the tree split.
If more extents are inserted, they could cause the whole tree
split more than once, but this is really rare.

Lustre always reserve extents in 1 extent case, this is wrong.
Also fix indirect blocks calculation.

LU-14732 utils: ensure hsm_user_request extent fields are zero

Another patch changed the linking flags for liblustreapi which
caused sanit-hsm 29c to fail. Debugging revealed the reason was
the extent fields in hsm_user_request sent to the kernel was
not zeroed out. For some reason the compiler flags hide this
bug. I found this is easily reproduced by removing
lhsmtool_posix_DEPENDENCIES which is not needed anyways since
the build system can calculate those dependencies for us.
Update the function llapi_hsm_user_request_alloc to zero out
the struct hsm_user_request allocated.

LU-10350 lod: adjust stripe count to available ost count

* In ost-pool.sh, reset $MOUNT's stripe offset, so that the created
  diretory will not inherit it from root directory.

* Preserve the root directory layout in replay-single (run before

LU-14711 osc: Notify server if cache discard takes a long time

Discarding a large number of pages from a mapping under a
single lock can take a really long time (750GB is over 170s).
Since there is no stream of RPCs sent to the server as with
read or write to prolong the DLM lock timeout, the server
may evict the client as it does not see progress is being made.

As such send periodic "empty" RPCs to the server to show the
client is still alive and working on the pages under the lock.

For compatibility reasons the RPC is formed as a one-byte
OST_READ request with a special flag set to avoid doing
actual IO, but older servers actually do the one-byte read

In lnet_peer_deletion(), we need to use lnet_del_init() when removing

LU-14660 lnet: Fix destination NID for discovery PUSH

If we're sending a discovery PUSH after receiving a discovery
REPLY then we want to send via the same NID that the reply was
sent to. This introduces a challenge in selecting an appropriate
destination NID for the PUSH because lnet_select_pathway() will not
run the MR selection algorithm for choosing a peer NI if the source
NI has been specified.

It is reasonable to assume that the NID used by the message
originator in sending the REPLY is a suitable destination for the
discovery PUSH. Thus, we record this NID in the same location we
currently record the lp_disc_src_nid, and use it when sending the
PUSH. With this change, the only other user of lnet_peer_select_nid()
is lnet_peer_send_ping(). In the ping case we do not set a source NID,
so lnet_select_pathway() is free to choose any peer NI. So this change
allows us to get rid of lnet_peer_select_nid() altogether.

Alternatively, we would need to reproduce a lot of the path selection
algorithm inside lnet_peer_select_nid() in order to avoid sending to
unhealthy NIDs. It seems undesirable and unnecessary to duplicate that
logic.

LU-9537 utils: implement "lfs getstripe --fid" for directories

Enhance the lfs command by displaying a directory fid when using "lfs
getstripe --fid" on one.

When displaying information through "lfs getstripe --fid", we would
check if the given path was associated to a directory or not. If so,
the fid display would just be skipped, showing a simple blank line.
However, a user could still find the fid of a directory by using "lfs
path2fid" on the same directory.  Therefore, this patch adds a hook to
the underlying "llapi_fd2fid()" (called internally by "lfs path2fid")
when trying to display a directory fid with "lfs getstripe --fid".

LU-14673 sec: annotate algorithms taking optional key

Crypto algorithms implementing a ->setkey() method but that can also
be used without a key must set the CRYPTO_ALG_OPTIONAL_KEY flag if
defined in the kernel.
In Lustre, adler32 implementation defines a ->setkey() method, but
its "key" is not actually a cryptographic key.

LU-14565 ofd: Do not rely on tgd_blockbit

LU-10948 llite: Introduce inode open heat counter

Initial framework to support detection of naive apps that
assume open-closes are "free" and proceed to open/close
same files between minute operations.

We will track number of file opens per inode and last time inode
was closed.

Initially we'll expose these controls:
llite/opencache_threshold_count - enables functionality and controls after how
                                  many opens open lock is requested
llite/opencache_threshold_ms    - if any reopen happens within this time (in
                                  ms), the open would trigger open lock request
llite/opencache_max_ms          - If last close was longer than this many ms
                                  ago - start counting opens from zero again

Once enough useful data is collected we can look into adding a heatmap
or another similar mechanism to better manage it and enable it
by default with sensible settings.

LU-14627 tests: Create unload_modules_local

t-f allows for loading modules on single node via load_modules_local.
However, there is no corresponding unload_modules_local that can be
called to cleanup after call to load_modules_local, so we create it.
unload_modules() refactored to use unload_modules_local.

Also address a potential issue that can prevent LND modules from
unloading. Some LNet setup (particularly those in sanity-lnet) may
require that we call lnetctl lnet unconfigure (or lctl net down)
to drop a ref on the module before it can be unloaded.

LU-13912 lnet: Correct the router ping interval calculation

The router ping interval is being divided by the number of local nets
which results in sending pings more frequently than defined by the
alive_router_check_interval. In addition, the current code is structured
such that we may not find a peer net in need of a ping until after
inspecting the router list multiple times. Re-work the code so that the
loop that inspects a router's peer nets will look at all of them until
it either loops back around the list or it finds one that actually
needs to be pinged.

We also move the check of LNET_PEER_RTR_DISCOVERY so that we avoid the
work of inspecting the router's peer nets if the router is already being
discovered.

LU-14641 osd-ldiskfs: write commit declaring improvement

1)extent bytes could be missed to increase with less than
1M, fix to to compare it with current value, and decay
it for every allocation.

2)with system space usage growing up, mballoc codes won't
try best to scan block group to align best free extent as
we can. So extent bytes per extent could be decayed to a
very small value, this could make us reserve too many credits.
We could be more optimistic in the credit reservations, even
in a case where the filesystem is nearly full, it is extremely
unlikely that the worst case would ever be hit.

3)Add extent bytes stats and debug ability to analysis
over reservation problem.
