There are two sites are not subpage compatible yet for extent_write_locked_range(): - How @nr_pages are calculated For subpage we can have the following range with 64K page size: 0 32K 64K 96K 128K | |////|/////| | In that case, although 96K - 32K == 64K, thus it looks like one page is enough, but the range spans two pages, not one. Fix it by doing proper round_up() and round_down() to calculate @nr_pages. Also add some extra ASSERT()s to ensure the range passed in is already aligned. - How the page end is calculated Currently we just use cur + PAGE_SIZE - 1 to calculate the page end. Which can't handle the above range layout, and will trigger ASSERT() in btrfs_writepage_endio_finish_ordered(), as the range is no longer covered by the page range. Fix it by taking page end into consideration. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
