      f2fs: fix iget/iput of dir during recovery · 5deb8267
      Jaegeuk Kim authored 
      It is possible that iput is skipped after iget during the recovery.

In recover_dentry(),
 dir = f2fs_iget();
 ...
 if (de && inode->i_ino == le32_to_cpu(de->ino))
	goto out;

In this case, this dir is not able to be added in dirty_dir_inode_list.
The actual linking is done only when set_page_dirty() is called.

So let's add this newly got inode into the list explicitly, and put it at the
end of the recovery routine.

      f2fs: reorganise the function get_victim_by_default · b2b3460a
      Namjae Jeon authored 
      Fix the function get_victim_by_default, where it checks
for the condition  that p.min_segno != NULL_SEGNO as
shown:

if (p.min_segno != NULL_SEGNO)
           goto got_it;

and if above condition is true then

got_it:
        if (p.min_segno != NULL_SEGNO) {

So this condition is being checked twice. Hence move the goto
statement after the if condition so that duplication of condition
check is avoided.

Also this function makes a call to get_max_cost() to compute
the max cost based on the f2fs_sbi_info and victim policy. Since
get_max_cost depends on on three parameters of victim_sel_policy
=> alloc_mode, gc_mode & ofs_unit, once this victim policy is
initialised, these value will not change till the execution
time of get_victim_by_default() & also f2fs_sbi_info structure
parameters will not change.

Hence making calls to get_max_cost() in while loop does not seems to
be a good point. Instead we can call it once in begining and store
the results in local variable, which later can serve our purpose
for comparing the cost with max cost inside the while loop.

      ipc/sem.c: Fix missing wakeups in do_smart_update_queue() · ab465df9
      Manfred Spraul authored 
      do_smart_update_queue() is called when an operation (semop,
semctl(SETVAL), semctl(SETALL), ...) modified the array.  It must check
which of the sleeping tasks can proceed.

do_smart_update_queue() missed a few wakeups:
 - if a sleeping complex op was completed, then all per-semaphore queues
   must be scanned - not only those that were modified by *sops
 - if a sleeping simple op proceeded, then the global queue must be
   scanned again

And:
 - the test for "|sops == NULL) before scanning the global queue is not
   required: If the global queue is empty, then it doesn't need to be
   scanned - regardless of the reason for calling do_smart_update_queue()

The patch is not optimized, i.e.  even completing a wait-for-zero
operation causes a rescan.  This is done to keep the patch as simple as
possible.
