Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

Pull ext4 updates from Ted Ts'o:
 "There are a number of major cleanups in ext4 this cycle:

   - The data=journal writepath has been significantly cleaned up and
     simplified, and reduces a large number of data=journal special
     cases by Jan Kara.

   - Ojaswin Muhoo has replaced linked list used to track extents that
     have been used for inode preallocation with a red-black tree in the
     multi-block allocator. This improves performance for workloads
     which do a large number of random allocating writes.

   - Thanks to Kemeng Shi for a lot of cleanup and bug fixes in the
     multi-block allocator.

   - Matthew wilcox has converted the code paths for reading and writing
     ext4 pages to use folios.

   - Jason Yan has continued to factor out ext4_fill_super() into
     smaller functions for improve ease of maintenance and
     comprehension.

   - Josh Triplett has created an uapi header for ext4 userspace API's"
