LU-5885 lfsck: deadlock when remove striped dir

There is potential deadlock race condition between removing
striped directory and namespace LFSCK. Consider the following
scenario:

1) The LFSCK thread obtained the master object firstly, at
   that time, the master object has not been destroyed yet.

2) One RPC service thread destroyed the master and all its
   slave objects (shards). Because the LFSCK is referencing
   the master object, then the master object will be marked
   as dying in RAM. On the other hand, the master object is
   referencing all its slave objects, then all slave objects
   will be marked as dying in RAM also.

3) The LFSCK thread tries to find some slave object with the
   master object referenced. Then it will find that the slave
   object is dying. According to the object visibility rules:
   the object with dying flag cannot be returned to others.
   So the LFSCK thread has to wait until the dying object has
   been purged from RAM, then it can allocate a new object (with
   the same FID) in RAM. Unfortunately, the LFSCK thread itself
   is referencing the master object, and cause the master object
   cannot be purged, then cause the slave object cannot be purged
   also. So the LFSCK thread will fall into deadlock.

To resolve such trouble, the LFSCK should use non-blocked version
lu_object_find() to locate the slave object of the striped dir,
and return failure immediately (instead of wait) when it finds
dying (slave) object.

This patch also contorls the async pipeline depth between the
LFSCK main engine and the namespace assistant thread to avoid
potential RAM pressure.

Some other code adjustment to avoid potential data overflow
that may cause weird LFSCK statistics information.

LU-5443 libcfs: replace direct HZ access with kernel APIs

On some customer's systems, kernel was compiled with HZ defined to
100, instead of 1000. This improves performance for HPC applications.
However, to use these systems with Lustre, customers have to re-build
Lustre for the kernel because Lustre directly uses the defined
constant HZ.

Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.

These kernel APIs include:
 jiffies_to_msecs()
 jiffies_to_usecs()
 jiffies_to_timespec()
 msecs_to_jiffies()
 usecs_to_jiffies()
 timespec_to_jiffies()

And here are some samples of the replacement:
 HZ            -> msecs_to_jiffies(MSEC_PER_SEC)
 n * HZ        -> msecs_to_jiffies(n * MSEC_PER_SEC)
 HZ / n        -> msecs_to_jiffies(MSEC_PER_SEC / n)
 n / HZ        -> jiffies_to_msecs(n) / MSEC_PER_SEC
 n / HZ * 1000 -> jiffies_to_msecs(n)

This patch replaces the direct HZ access in libcfs module.

The patch also replaces ONE_BILLION with NSEC_PER_SEC,
and ONE_MILLION with USEC_PER_SEC in linux-time.h.

constant HZ.

Since kernel 2.6.21, some non-HZ dependent timing APIs become non-
inline functions, which can be used in Lustre codes to replace the
direct HZ access.

These kernel APIs include:
 jiffies_to_msecs()
 jiffies_to_usecs()
 jiffies_to_timespec()
 msecs_to_jiffies()
 usecs_to_jiffies()
 timespec_to_jiffies()

And here are some samples of the replacement:
 HZ            -> msecs_to_jiffies(MSEC_PER_SEC)
 n * HZ        -> msecs_to_jiffies(n * MSEC_PER_SEC)
 HZ / n        -> msecs_to_jiffies(MSEC_PER_SEC / n)
 n / HZ        -> jiffies_to_msecs(n) / MSEC_PER_SEC
 n / HZ * 1000 -> jiffies_to_msecs(n)

This patch replaces the direct HZ access in ldiskfs module.

nodemap_add_member can't be used to move an already hashed member
to a new nodemap, so this patch copies the needed functionality to
nm_member_reclassif_cb. This also adds a mutex lock for reclassifying

Reclassifying takes a lock on a nodemap's nm_member_hash, so a
deadlock could arise if one nodemap is trying to add a member to
another nodemap, and that second nodemap is also reclassifying and
eventually tries to add a member to the first nodemap.

LU-5912 libcfs: use vfs api for fsync calls

Use vfs_fsync_range() instead of direct use of filp->f_op->fsync()
routines.  Doing so will apply correct locking transparently without
needing to decide how to do it ourselves.
What we were doing was a long term violation of the locking
protocols described in Documentation/filesystems/Locking in linux
source but was never noticed until new checking code went into the
RHEL 6.6 kernel.  The new check triggered a visible error in syslog.

LU-1453 scrub: auto trigger OI scrub more flexible

Generally, scanning the whole device for OI scrub routine check may
takes some long time. If the whole system only contains several bad
OI mappings, then it is not worth to trigger OI scrub automatically
with full speed when some bad OI mapping is auto-detected. Instead,
we can make the OI scrub to fix the found bad OI mappings only, and
if more and more bad OI mappings are found as to exceeds some given
threshold that can be adjusted via some proc interface, then the OI
scrub will run with full speed to scan whole device.

Currently, we offer two kinds of thresholds for triggering OI scrub
to scan the whole device:

1) "the total OI mappings count" vs "the bad OI mappings count".
   If such ratio is low than the given threshold that can be set
   via the proc interface "full_scrub_ratio", then trigger urgent
   mode OI scrub.

2) "the speed of found the bad OI mappings". If the speed exceeds
   the given threshold that can be adjusted via the proc interface
   "full_scrub_speed", then trigger urgent mode OI scrub.

LU-5727 ldlm: revert the changes for lock canceling policy

The changes for LRU lock policy was introduced by commit bfae5a4e,
where I was trying to revise the policy to pick locks for canceling.

However, this caused two problems as mentioned in LU-5727. The first
problem is that the lock can only be picked for canceling only if
the number of LRU locks is over preset LRU number AND it's aged; the
second problem is that mdc_cancel_weight() tends to not cancel OPEN
locks, therefore open locks can be kept forever and finally exhausts
memory on the MDT side.

The first problem is fixed by patch e8812867. This patch will revert
the rest of changes related to LRU policy revise.

1. Application calls ll_close_inode_openhandle()-> mdc_close(),

2. Before the md_clear_open_replay_data() is called for close,

   mistakenly;

3. Open replay interpret callback (mdc_replay_open) could race

This patch fix the ptlrpc_free_committed() to make sure the

LU-5079 tests: fix service_time in max_recovery_time()

This patch fixes the calculation of service_time in
max_recovery_time() to use the new method in
check_and_start_recovery_timer() and new values of
CONNECTION_SWITCH_MAX and CONNECTION_SWITCH_INC.

The patch also fixes replay-dual sub-tests:

  uncertain time in test_11()
- to add some margin into the recovery time comparison
  in test_20()

Limit the value set by mount.lustre set_blockdev_tunables() to a
reasonable 32MB instead of the maximum possible amount, since the

LU-5707 lfsck: store namespace LFSCK statistics info in new EA

For Lustre-2.6 or older release, the namespace LFSCK statistics info
was stored as XATTR_NAME_LFSCK_NAMESPACE EA, but in Lustre-2.7, the
namespace LFSCK will introduce more statistics information that will
cause the XATTR_NAME_LFSCK_NAMESPACE EA to be extended. If it still
uses the old XATTR_NAME_LFSCK_NAMESPACE EA, then when downgrade, the
old LFSCK will get -ERANGE when load the new trace file from disk,
and then the LFSCK cannot be started after downgrade.

To avoid such trouble, Lustre-2.7 will use new EA to store the
namespace LFSCK statistics info: XATTR_NAME_LFSCK_NAMESPACE_V2,
and keep a dummy XATTR_NAME_LFSCK_NAMESPACE EA in the trace file
to be compatible with old LFSCK.

modifying BH_LRU_SIZE, it was proposed to directly set it
to 16. This has been accepted.
This patch is merged in the upstream kernel:

LU-5833 lfsck: handle lfsck_open_dir() return-value properly

Inside the lfsck_prep(), the returned value from lfsck_open_dir()
should be handled properly before returning to the caller directly.
For example: positive number from lfsck_open_dir() means the end of
current directory, but if continuously return such value to the
lfsck_prep()'s caller, then the whole LFSCK first-stage scanning
will be regarded as done by wrong.

LU-5817 clio: Do not allow group locks with gid 0

When a group lock with GID=0 is released (put_grouplock is
called), an assertion in cl_put_grouplock is hit.

We should not allow group lock requests with GID=0, instead
we should return -EINVAL.

Also fix random_group_id so it never returns gid==0.
