struct timespec is also not y2038 safe.  Retain timespec for timestamp
representation here as lustre uses it internally everywhere.  These
references will be changed to use struct timespec64 in a separate patch.

This is also in preparation for the patch that transitions vfs

along with this change.

CURRENT_TIME macro will be deleted before merging the aforementioned

LU-9597 ofd: fix race for project setattr

sanity-quota 33 exposed an intresting project quota bug,
problem is we could hit following condition:

step 1: create an empty file
step 2: buffer write data to file, at this time project id 0 is packed.
step 3: chattr file's project id

If write RPC is generated on client but not reaching OST yet, and step 3
chattr is issued in this time window and chattr on OST is done before
write PRC being processed on OST:

That means we have changed file's project ID, but ofd_attr_handle_id()
did not clear S_ISUID and S_ISGID for this case. Write RPC arrived on
OST, first write RPC will call ofd_attr_handle_id() to set attribute.
Unfortunately it will think this is first write as S_ISUID and S_ISGID
is set, project id will be reset with packed id 0, thus we got wrong
project accounting.

We should use another file mode to indicate whether
project id has been initialized, this patch tries to
fix this problem.

LU-8066 libcfs: migrate to debugfs

move /proc/sys/lnet to debugfs

Parameters in lnet sysctl are of debug quality, so let's move them
to debugfs instead.

Linux-commit: 0871d551af37c72c308397c16c31bae945e6a79d

Remove redundant lnet debugfs variables

/proc/sys/lnet/console_ratelimit, debug_path and panic_on_lbug
are module parameters with no special magic accessible via
/sys/module/libcfs/parameters/libcfs_console_ratelimit,
/sys/module/libcfs/parameters/libcfs_debug_file_path and
/sys/module/libcfs/parameters/libcfs_panic_on_lbug respectively.

As such just replace them with corresponding symlinks

Linux-commit: 1b4d97b6c6ca05446ff33843a7b174cdd765df5a

get rid of debugfs/lnet/console_backoff

module parameter libcfs_console_backoff accessible through
/sys/module/libcfs/parameters/libcfs_console_backoff would
do the same thing, just add a special "uintpos" parameter
type to disallow 0 values too.

Also add a symlink to the module parameter variable for
backwards compatibility

Linux-commit: 8710427dd68f4dff8976d221e220317cea20ecec

get rid of debugfs/lnet/debug_mb

It's just a fancy libcfs_debug_mb module parameter wrapper,
so just add debug buffer size check and resizing and the same
functionality now would be accessible via
/sys/module/libcfs/parameters/libcfs_debug_mb

Also add a symlink for backwards compatibility.

Linux-commit: aa66d6f87f300b15ac2efdcde9e198bf5a9020ce

Properly handle debugfs read- and write-only files

It turns out that unlike procfs, debugfs does not really enforce
permissions for root (similar to regular filesystems), so we need
to ensure we are not providing ->write() method to read-only files
and ->read() method for write-only files at registration.

This fixes a couple of crashes on unexpected access.

memory described by the MD.

There are three scenarios that must be handled:
1. The memory is described by an lnet_kiov_t structure
 -> this describes kernel pages
2. The memory is described by a struct kvec
 -> this describes kernel logical addresses
3. The memory is a contiguous buffer allocated via vmalloc

For case 1 and 2 we look at the first vector which contains
the data to be DMAed, taking into consideration the msg offset.

For case 2 we have to take the extra step of translating the kernel
logical address to a physical page using virt_to_page() macro.

For case 3 we need to use is_vmalloc_addr() and vmalloc_to_page to
get the associated page to be able to identify the CPT.

o2iblnd uses the same strategy when it's mapping the memory into
a scatter/gather list. Therefore, lnet_kvaddr_to_page() common
function was created to be used by both the o2iblnd and
lnet_cpt_of_md()

kmap_to_page() performs the high memory check which
lnet_kvaddr_to_page() does. However, unlike the latter it handles
the highmem case properly instead of calling LBUG. It's not
100% clear why the code was written that way. Since the legacy
code will need to still be maintained, adding kmap_to_page() will
not simplify the code. Furthermore, the behavior for kernels
which export kmap_to_page() will be different from kernels which
do not. At worst calling kmap_to_page() might mask some problems
which would've been caught by the LBUG earlier on. However, at
the time of this fix, that LBUG has never been observed.

LU-7988 hsm: run HSM coordinator once per second at most

When there is heavy HSM usage, each new HSM request can trigger the
HSM coordinator, which may run many times per seconds. When it is
running it locks the HSM catalog (using cdt_llog_lock) preventing any
other HSM operation to happen, such as insertion, removal or dumping
of the requests.

Limit the coordinator to run once per second, and only if there is
work to do. It will still execute the loop once every 10 seconds (or
as defined by the procfs loop_period parameter) to do housekeeping.

LU-6210 utils: Use C99 initializers in lfs_getstripe_internal

This patch makes no functional changes.  Struct initializers that
use C89 or GCC-only syntax are updated to C99 syntax.

C89 positional initializers require values to be placed in the
correct order. This will cause errors if the fields of the struct
definition are reordered or fields are added or removed. C99 named

This patch updates lfs_getstripe_internal() to use the C99 syntax.

LU-9728 osd: use GFP_HIGHUSER for non-local IO

When the obdfilter code was split into separate OFD and OSD modules,
the bulk IO page allocation was implemented to use GFP_NOFS to avoid
allocations recursing into the filesystem and causing deadlocks.

However, this is only possible if the RPC is coming from a local
client, as we might end up waiting on a page sent in the request we're
serving. Local RPCs use __GFP_HIGHMEM so that the pages can use all of
the available memory on the OSS on 32-bit machines.

It is possible to use more aggressive GFP_HIGHUSER flags for non-local
clients to be able to generate more memory pressure on the OSS and
allow inactive pages to be reclaimed, since the OSS doesn't have any
other processes or allocations that generate memory reclaim pressure.

See also b=17576 (bdf50dc9) and b=19529 (3dcf18d3) for details.

The patch also implements an LNet function to determine if a client NID
is local or not.  This becomes more complex in the LNet Multi-Rail world
and it is really LNet's job to handle NIDs, not that of Lustre.

LU-8760 lib: avoid unexpected out of order execution

There is race condtion in __l_wait_event() because of the
out-of-order execution between changing thread state and
checking condition. It may block the thread (to be waken)
for ever. Consider the following real execution order:

1. Thread1 checks condition on CPU1, gets false.
2. Thread2 sets condition on CPU2.
3. Thread2 calls wake_up() on CPU2 to wake the threads with
   state TASK_INTERRUPTIBLE | TASK_UNINTERRUPTIBLE. But the
   Thread1'sstate is TASK_RUNNING at that time.
4. Thread1 sets its state as TASK_INTERRUPTIBLE on CPU1,
   then schedule.

If the '__timeout' variable is zero, the Thread1 will have
no chance to check the condition again.

Generally, the interval between out-of-ordered step1 and step4
is very tiny, as to above step2 and step3 cannot happen. On some
degree, it can explain why we seldom hit related trouble. But
such race really exists, especially consider that the step1 and
step4 can be interruptible.

The patch adds barrier between changing thread's state and
checking condition to avoid out-of-order execution.

LU-6210 utils: Use C99 struct initializer in parse_opts()

This patch makes no functional changes.  The long_opt initializer in
parse_opts() is updated to C99 syntax, and renamed to long_opts for
consistency.

C89 positional initializers require values to be placed in the
correct order. This will cause errors if the fields of the struct
definition are reordered or fields are added or removed. C99 named
initializers avoid this problem, and also automatically clear any
values that are not explicitly set.
