commit 2dd15654ac0abe587a245a09a7823bbbd588bfb7 upstream.
In f2fs_fill_super, if there is any IO error occurs during recovery,
cached discard entries will be leaked, in order to avoid this, make
write_checkpoint() handle memory release by itself, besides, move
clear_prefree_segments to write_checkpoint for readability.

commit 2411cf5befa5804e4ced4c45a3212d7653869286 upstream.
During nid allocation, it needs to exclude building and allocating flow
of free nids, this is because while building free nid cache, there are two
steps: a) load free nids from unused nat entries in NAT pages, b) update
free nid cache by checking nat journal. The two steps should be atomical,
otherwise an used nid can be allocated as free one after a) and before b).
This patch adds missing lock which covers build_free_nids in
unlock_operation and f2fs_balance_fs_bg to avoid that.

In the last ilen case, i was already increased, resulting in accessing out-

Fix to check ilen first to exit the loop.

Exception event can be raised by the device when system
suspend is in progress. This will result in unclocked
register access in exception event handler as clocks will
be turned off during suspend. This change makes sure to flush
exception event handler work in suspend before disabling
clocks to avoid unclocked register access issue.

This reverts commit c5616f2f874faa20b59b116177b99bf3948586df.
If we re-init the per-cpu boostgroup spinlock every time that
we add a new boosted cgroup, we can easily wipe out (reinit)
a spinlock struct while in a critical section. We should only
be setting up the per-cpu boostgroup data, and the spin_lock
initialization need only happen once - which we're already
doing in a postcore_initcall.
For example:
-------- CPU 0 -------- | -------- CPU1 --------
cgroupX boost group added |
schedtune_enqueue_task |
acquires(bg->lock) | cgroupY boost group added
| for_each_cpu()
| raw_spin_lock_init(bg->lock)
releases(bg->lock) |
BUG (already unlocked) |

This results in the following BUG from the debug spinlock code:

HDR playback needs metadata to be sent to the sink
while the playback is ongoing and needs a proper
teardown sequence when the playback has ended with respect
to the infoframe being sent to the sink.
This needs a state machine to synchronize start/stop of
the playback with sending the right metadata along with
resetting the infoframe HDMI registers.
Add support for this HDR playback control state machine.
