fix: sched: Change task_struct::state (v5.14)
See upstream commit:
commit 2f064a59a11ff9bc22e52e9678bc601404c7cb34
Author: Peter Zijlstra <email address hidden>
Date: Fri Jun 11 10:28:17 2021 +0200
sched: Change task_struct::state
Change the type and name of task_struct::state. Drop the volatile and
shrink it to an 'unsigned int'. Rename it in order to find all uses
such that we can use READ_ONCE/WRITE_ONCE as appropriate.
btrfs: pass btrfs_inode to btrfs_writepage_endio_finish_ordered()
There is a pretty bad abuse of btrfs_writepage_endio_finish_ordered() in
end_compressed_bio_write().
It passes compressed pages to btrfs_writepage_endio_finish_ordered(),
which is only supposed to accept inode pages.
Thankfully the important info here is the inode, so let's pass
btrfs_inode directly into btrfs_writepage_endio_finish_ordered(), and
make @page parameter optional.
By this, end_compressed_bio_write() can happily pass page=NULL while
still getting everything done properly.
Also, to cooperate with such modification, replace @page parameter for
trace_btrfs_writepage_end_io_hook() with btrfs_inode.
Although this removes page_index info, the existing start/len should be
enough for most usage.

Sync `show_inode_state()` macro with upstream stable kernels
The following commit was backported to multiple stable branches:
commit 5fcd57505c002efc5823a7355e21f48dd02d5a51
Author: Jan Kara <email address hidden>
Date: Fri May 29 16:24:43 2020 +0200
writeback: Drop I_DIRTY_TIME_EXPIRE
The only use of I_DIRTY_TIME_EXPIRE is to detect in
__writeback_single_inode() that inode got there because flush worker
decided it's time to writeback the dirty inode time stamps (either
because we are syncing or because of age). However we can detect this
directly in __writeback_single_inode() and there's no need for the
strange propagation with I_DIRTY_TIME_EXPIRE flag.

fix: block: remove disk_part_iter (v5.12)
In v5.12 a refactoring of the genhd code was started and the symbols
related to 'disk_part_iter' were unexported. In v5.13 they were
completely removed.
This patch replaces the short lived compat code that is specific to
v5.12 and replaces it with a generic internal implementation that
iterates directly on the 'disk->part_tbl' xarray which will be used
on v5.12 and up.
This seems like a better option than keeping the compat code that will
only work on v5.12 and make maintenance more complicated. The compat was
backported to the stable branches but isn't yet part of a point release
so can be safely replaced.
Just open code the xa_for_each in the remaining user.

block: use an xarray for disk->part_tbl
Now that no fast path lookups in the partition table are left, there is
no point in micro-optimizing the data structure for it. Just use a bog
standard xarray.
