When KVM maps a largepage backed region at a lower level in order to make it executable (i.e. NX large page shattering), it reduces the TLB performance of that region. In order to avoid making this degradation permanent, KVM must periodically reclaim shattered NX largepages by zapping them and allowing them to be rebuilt in the page fault handler. With this patch, the TDP MMU does not respect KVM's rate limiting on reclaim. It traverses the entire TDP structure every time. This will be addressed in a future patch. Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell machine. This series introduced no new failures.

Dirty logging ultimately breaks down MMU mappings to 4k granularity. When dirty logging is no longer needed, these granaular mappings represent a useless performance penalty. When dirty logging is disabled, search the paging structure for mappings that could be re-constituted into a large page mapping. Zap those mappings so that they can be faulted in again at a higher mapping level. Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell machine.

Pull clk updates from Stephen Boyd: "This contains no changes to the core framework. It is a collection of various clk driver updates. The biggest driver updates in terms of lines of code is the Allwinner driver, closely followed by the Qualcomm and Mediatek drivers. All of those hit high because we add so many lines of clk data. Coming in fourth place is i.MX which also adds a bunch of clk data. This accounts for the new driver additions this time around. Otherwise the patches are lots of little cleanups and fixes for various clk drivers that have baked in linux-next for a while. I suppose one highlight or theme is that more clk drivers are being updated to work as modules, which is interesting to see such critical SoC infrastructure work as a loadable module.

Pull ext4 updates from Ted Ts'o: "The siginificant new ext4 feature this time around is Harshad's new fast_commit mode. In addition, thanks to Mauricio for fixing a race where mmap'ed pages that are being changed in parallel with a data=journal transaction commit could result in bad checksums in the failure that could cause journal replays to fail. Also notable is Ritesh's buffered write optimization which can result in significant improvements on parallel write workloads. (The kernel test robot reported a 330.6% improvement on fio.write_iops on a 96 core system using DAX) Besides that, we have the usual miscellaneous cleanups and bug fixes" Link: https://lore.kernel.org/r/20200925071217.GO28663@shao2-debian * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (46 commits) ext4: fix invalid inode checksum ext4: add fast commit stats in procfs ext4: add a mount opt to forcefully turn fast commits on ext4: fast commit recovery path jbd2: fast commit recovery path ext4: main fast-commit commit path jbd2: add fast commit machinery ext4 / jbd2: add fast commit initialization ext4: add fast_commit feature and handling for extended mount options doc: update ext4 and journalling docs to include fast commit feature ext4: Detect already used quota file early jbd2: avoid transaction reuse after reformatting ext4: use the normal helper to get the actual inode ext4: fix bs < ps issue reported with dioread_nolock mount opt ext4: data=journal: write-protect pages on j_submit_inode_data_buffers() ext4: data=journal: fixes for ext4_page_mkwrite() jbd2, ext4, ocfs2: introduce/use journal callbacks j_submit|finish_inode_data_buffers() jbd2: introduce/export functions jbd2_journal_submit|finish_inode_data_buffers() ext4: introduce ext4_sb_bread_unmovable() to replace sb_bread_unmovable() ext4: use ext4_sb_bread() instead of sb_bread() ...

The IO_REPARSE_TAG_LX_ tags originally were used by WSL but they are preferred by the Linux client in some cases since, unlike the NFS reparse tag (or EAs), they don't require an extra query to determine which type of special file they represent. Add support for readdir to recognize special file types of FIFO, SOCKET, CHAR, BLOCK and SYMLINK. This can be tested by creating these special files in WSL Linux and then sharing that location on the Windows server and mounting to the Windows server to access them. Prior to this patch all of the special files would show up as being of type 'file' but with this patch they can be seen with the correct file type as can be seen below: brwxr-xr-x 1 root root 0, 0 Oct 21 17:10 block crwxr-xr-x 1 root root 0, 0 Oct 21 17:46 char drwxr-xr-x 2 root root 0 Oct 21 18:27 dir prwxr-xr-x 1 root root 0 Oct 21 16:21 fifo -rwxr-xr-x 1 root root 0 Oct 21 15:48 file lrwxr-xr-x 1 root root 0 Oct 21 15:52 symlink-to-file TODO: go through all documented reparse tags to see if we can reasonably map some of them to directories vs. files vs. symlinks and also add support for device numbers for block and char devices.

The "end" pointer is either NULL or it points to the next byte to parse. If there isn't a next byte then dereferencing "end" is an off-by-one out of bounds error. And, of course, if it's NULL that leads to an Oops. Printing "*end" doesn't seem very useful so let's delete this code. Also for the last debug statement, I noticed that it should be printing "sequence_end" instead of "end" so fix that as well. Reported-by:

This and related patches which move mount related code to fs_context.c has the advantage of shriking the code in fs/cifs/connect.c (which had the second most lines of code of any of the files in cifs.ko and was getting harder to read due to its size) and will also make it easier to switch over to the new mount API in the future.
