The esai_ahb clock is derived from ahb and used to provide ESAI the
capability of register accessing and FSYS clock source for I2S clocks
dividing. The gate bits of this esai_ahb clock are shared with the
esai clock -- the baud clock, so we need to call imx_clk_gate2_shared()
for these two clocks.

It's quite common on i.MX that one gate bit controls the gating of
multiple clocks, i.e. this is a shared gate. The patch adds the
function imx_clk_gate2_shared() for such case. The clocks controlled
by the same gate bits should call this function with a pointer to a
single share count variable, so that the gate bits will only be
operated on the first enabling and the last disabling of these shared
gate clocks.
Thanks to Gerhard Sittig <gsi@denx.de> for this idea.

The imx specific clk_gate2 always has a valid lock with the clock. So
the validation on gate->lock is not really needed. Remove it.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
The imx clk-gate2 driver implements an i.MX specific gate clock, which
has two bits controlling the gate states. While this is a completely
separate gate driver from the common clk-gate one, it reuses the common
clk_gate structure. Such reusing makes the extending of clk_gate2
clumsy. Let's define struct clk_gate2 on our own to make the driver
independent of the common clk-gate one, and ease the clk_gate2 extending
at a later time.

Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
After returning from the chain that we just went to with no matchings,
we get a bogus rule number in the trace. To fix this, we would need
to iterate over the list of remaining rules in the chain to update the
rule number counter.
Patrick suggested to set this to the maximum value since the default
base chain policy is the very last action when the processing the base
chain is over.

This patch fixes a crash when trying to access the counters and the

via the goto chain. Fix this by falling back on the original base
chain after returning from the custom chain.
While fixing this, kill the inline function to account chain statistics

On a bigalloc,^flex_bg filesystem, the ext4_valid_block_bitmap
function fails to convert from blocks to clusters when spot-checking
the validity of the bitmap block that we've just read from disk. This
causes ext4 to think that the bitmap is garbage, which results in the
block group being taken offline when it's not necessary. Add in the
necessary EXT4_B2C() calls to perform the conversions.

The ext4_bg_has_super() function doesn't know about the new rules for

block bitmap initialization doesn't know that it shouldn't reserve

When we perform a data integrity sync we tag all the dirty pages with
PAGECACHE_TAG_TOWRITE at start of ext4_da_writepages. Later we check
for this tag in write_cache_pages_da and creates a struct
mpage_da_data containing contiguously indexed pages tagged with this
tag and sync these pages with a call to mpage_da_map_and_submit. This
process is done in while loop until all the PAGECACHE_TAG_TOWRITE
pages are synced. We also do journal start and stop in each iteration.
journal_stop could initiate journal commit which would call
ext4_writepage which in turn will call ext4_bio_write_page even for
delayed OR unwritten buffers. When ext4_bio_write_page is called for
such buffers, even though it does not sync them but it clears the
PAGECACHE_TAG_TOWRITE of the corresponding page and hence these pages
are also not synced by the currently running data integrity sync. We
will end up with dirty pages although sync is completed.
This could cause a potential data loss when the sync call is followed
by a truncate_pagecache call, which is exactly the case in
collapse_range. (It will cause generic/127 failure in xfstests)
To avoid this issue, we can use set_page_writeback_keepwrite instead of
set_page_writeback, which doesn't clear TOWRITE tag.
