iio: 104-quad-8: Fix off-by-one error when addressing flag register
The flag register is offset by 1 from the respective channel data
register. This patch fixes an off-by-one error when attempting to read a
channel flag register where the base address was not properly offset.

The replay cursor should be updated properly when close happened

- replay cursor is moved to an open request during replay;
- application close that open file, so the rq_replay of the open

- ptlrpc_replay_next() calls ptlrpc_free_committed() to free
committed/closed requests, the open request is removed from

1. With two separated replay lists and replay cursor introduced,
finding replay request won't take much time as before, it's

2. Nowadays there are various kind of non-replay requests are

The 'fld_read_server' uses 'RMF_GENERIC_DATA' to hold the 'FLD_QUERY'

is not registered swabber function for 'RMF_GENERIC_DATA'. So the RPC
peers need to handle the RPC reply with fixed little-endian format.
In theory, we can define new structure with some swabber registered
to handle the 'FLD_QUERY' RPC reply result automatically. But from
the implementation view, it is not easy to be done within current
'struct req_msg_field' framework. Because the sequence range array
in the RPC reply is not fixed length, instead, its length depends
on 'lu_seq_range' count, that is unknown when prepare the RPC buffer.
Generally, for such flexible length RPC usage, there will be a field
in the RPC layout to indicate the data length. But for the 'FLD_READ'
RPC, we have no way to do that unless we add new length filed that
will broken the on-wire RPC protocol and cause interoperability
trouble with old peer.

Originally, the logic of handling config_llog_data::cld_refcount
is some confusing, it may cause the cld_refcount to be leaked or
trigger "LASSERT(atomic_read(&cld->cld_refcount) > 0);" when put
the reference. This patch clean related logic as following:
1) When the 'cld' is created, its reference is set as 1.
2) No need additional reference when add the 'cld' into the list
'config_llog_list'.
3) Inrease 'cld_refcount' when set lock data after mgc_enqueue()
done successfully by mgc_process_log().
4) When mgc_requeue_thread() traversals the 'config_llog_list',
it needs to take additional reference on each 'cld' to avoid
being freed during subsequent processing. The reference also
prevents the 'cld' to be dropped from the 'config_llog_list',
then the mgc_requeue_thread() can safely locate next 'cld',
and then decrease the 'cld_refcount' for previous one.
5) mgc_blocking_ast() will drop the reference of 'cld_refcount'
that is taken in mgc_process_log().
6) The others need to call config_log_find() to find the 'cld'
if want to access related config log data. That will increase
the 'cld_refcount' to avoid being freed during accessing. The
sponsor needs to call config_log_put() after using the 'cld'.
7) Other confused or redundant logic are dropped.
On the other hand, the patch also enhances the protection for
'config_llog_data' flags, such as 'cld_stopping'/'cld_lostlock'
as following.
a) Use 'config_list_lock' (spinlock) to handle the possible
parallel accessing of these flags among mgc_requeue_thread()
and others config llog data visitors, such as mount/umount,
blocking_ast, and so on.
b) Use 'config_llog_data::cld_lock' (mutex) to pretect other
parallel accessing of these flags among kinds of blockable
operations, such as mount, umount, and blocking ast.
The 'config_llog_data::cld_lock' is also used for protecting
the sub-cld members, such as 'cld_sptlrpc'/'cld_params', and
so on.

staging: lustre: hsm: stack overrun in hai_dump_data_field
The function hai_dump_data_field will do a stack buffer
overrun when cat'ing /sys/fs/lustre/.../hsm/actions if an action has
some data in it.
hai_dump_data_field uses snprintf. But there is no check for
truncation, and the value returned by snprintf is used as-is. The
coordinator code calls hai_dump_data_field with 12 bytes in the
buffer. The 6th byte of data is printed incompletely to make room for
the terminating NUL. However snprintf still returns 2, so when
hai_dump_data_field writes the final NUL, it does it outside the
reserved buffer, in the 13th byte of the buffer. This stack buffer
overrun hangs my VM.
Fix by checking that there is enough room for the next 2 characters
plus the NUL terminator. Don't print half bytes. Change the format to
02X instead of .2X, which makes more sense.

staging: lustre: obd: RCU stalls in lu_cache_shrink_count()
The algorithm for counting freeable objects in the lu_cache shrinker
does not scale with the number of cpus. The LU_SS_LRU_LEN counter
for each cpu is read and summed at shrink time while holding the
lu_sites_guard mutex. With a large number of cpus and low memory
conditions, processes bottleneck on the mutex.
This mod reduces the time spent counting by using the kernel's percpu
counter functions to maintain the length of a site's lru. The summing
occurs when a percpu value is incremented or decremented and a
threshold is exceeded. lu_cache_shrink_count() simply returns the
last such computed sum.
This mod also replaces the lu_sites_guard mutex with a rw semaphore.
The lock protects the lu_site list, which is modified when a file
system is mounted/umounted or when the lu_site is purged.
lu_cache_shrink_count simply reads data so it does not need to wait
for other readers. lu_cache_shrink_scan, which actually frees the
unused objects, is still serialized.
