Dentries are dynamically allocated and deallocated, and

nr_dentry seems to be 0 all the time. Hence it's safe to

assume that only nr_unused, age_limit and want_pages are

used. Nr_unused seems to be exactly what its name says.
|

Dentries are dynamically allocated and deallocated.
|
||||
|
||||
nr_dentry shows the total number of dentries allocated (active
|
||||
+ unused). nr_unused shows the number of dentries that are not
|
||||
actively used, but are saved in the LRU list for future reuse.
|
||||
|
||||
Age_limit is the age in seconds after which dcache entries
|
||||
can be reclaimed when memory is short and want_pages is
|
||||
nonzero when shrink_dcache_pages() has been called and the
|
||||
dcache isn't pruned yet.
|
||||
|
||||
nr_negative shows the number of unused dentries that are also
|
||||
negative dentries which do not mapped to actual files.

* instruction) prior to every ll instruction, in between it & any earlier
|
||||
* memory access instructions. Many of these cases are already covered by
|
||||
* smp_mb__before_llsc() but for the remaining cases, typically ones in
|
||||
* which multiple CPUs may operate on a memory location but ordering is not
|
||||
* usually guaranteed, we use loongson_llsc_mb() below.
|
||||
*
|

* This reordering case is fixed by 3A R2 CPUs, ie. 3A2000 models and later.

||||
* 2) If a conditional branch exists between an ll & sc with a target outside
|
||||
* of the ll-sc loop, for example an exit upon value mismatch in cmpxchg()
|
||||
* or similar, then misprediction of the branch may allow speculative
|
||||
* execution of memory accesses from outside of the ll-sc loop.
|
||||
*
|
||||
* In order to avoid this we need a memory barrier (ie. a sync instruction)
|
||||
* at each affected branch target, for which we also use loongson_llsc_mb()
|
||||
* defined below.
|
