Btw, I don't think this actually is safe without refcounting your kmap

Honestly the docs group is working on a publicly sharable
The pageblock_skip bitmap and cached scanner pfn's are two mechanisms in
compaction to prevent rescanning pages where isolation has recently failed
or they were scanned during the previous compaction attempt.
Currently, both kinds of information are updated via update_pageblock_skip(),
which is
The compaction free scanner is looking for PageBuddy() pages and skipping all
others. For large compound pages such as THP or hugetlbfs, we can save a lot
of iterations if we skip them at once using their compound_order(). This is
generally unsafe and we can read a bogus value of order due to a
The compaction migrate scanner tries to skip compound pages by their order, to
reduce number of iterations for pages it cannot isolate. The check is only done
if PageLRU() is true, which means it applies to THP pages, but not e.g.

Description: Digital signature
Compaction should finish when the migration and free scanner meet, i.e. they
reach the same pageblock. Currently however, the test in compact_finished()
simply just compares the exact pfns, which may yield a false negative when the
free scanner position is in the middle of a pageblock and the
This series is partly the cleanups that were posted as part of the RFC for
changing initial scanning positions [1] and partly new relatively simple
scanner optimizations (yes, they are still possible). I've resumed working
on the bigger scanner changes, but that will take a while, so no point in
Handling the position where compaction free scanner should restart (stored in
cc->free_pfn) got more complex with commit e14c720efdd7 ("mm, compaction:
remember position within pageblock in free pages scanner"). Currently the
position is updated in each loop iteration of isolate_freepages(),
Resetting the cached compaction scanner positions is now done implicitly in
__reset_isolation_suitable() and compact_finished(). Encapsulate the
functionality in a new function reset_cached_positions() and call it explicitly
where needed.

Use chained TRB mechanism to handle non maxpacket aligned transfers
greater than bounce buffer size. With this the first TRB will be programmed
to receive 'ALIGN(ur->length - maxp, maxp)' data and the second TRB
will be programmed to receive the remaining data using bounce buffer.

No functional change. This is in preparation for handling non maxpacket
aligned transfers greater than bounce buffer size. This is basically to
avoid code duplication when using chained TRB transfers to handle
non maxpacket aligned transfers greater than bounce buffer size.

No functional change. Added a new parameter in _dwc3_ep0_start_trans_ to
indicate whether the TRB is a chained TRB or last TRB. This is in
preparation for adding chained TRB support for ep0.

Patch series adds support to handle non maxpacket aligned transfers
greater than bounce buffer size (512). It first adds chained TRB
support and then uses it to handle non maxpacket aligned transfers
greater than bounce buffer size.
Also included a cleanup patch to use 'roundup' macro.
This
Add chained TRB support to ep0. Now TRB's can be chained just by
invoking _dwc3_ep0_start_trans_ with 'chain' parameter set to true.

No functional change. Used _roundup_ macro to calculate the transfer
size aligned to maxpacket in dwc3_ep0_complete_data. It also makes it
similar to how transfer size is calculated in __dwc3_ep0_do_control_data.

Take this out of the main .probe() routine in order to facilitate the
introduction of different ways to obtain 'duty cycle' information.
