Re: [PATCH 2/8] drm/i915/gem: Use PG_dropbehind instead of PG_reclaim

The recently introduced PG_dropbehind allows for freeing folios
immediately after writeback. Unlike PG_reclaim, it does not need vmscan
to be involved to get the folio freed.

Instead of using folio_set_reclaim(), use folio_set_dropbehind() in
__shmem_writeback()

It is safe to leave PG_dropbehind on the folio if, for some reason
(bug?), the folio is not in a writeback state after ->writepage().
In these cases, the kernel had to clear PG_reclaim as it shared a page
flag bit with PG_readahead.

I think this is correct
