  ext4: convert EXT4_B2C(sbi->s_stripe) users to EXT4_NUM_B2C (2024-09-03 22:14:17 -0400)

NOTE: git will report a merge conflict involving write_begin calls,
   but just taking the version from the ext4 branch should just work.
   See the test branch on the ext4.git branch for the test merge that I
   did my last round of regression tests before sending this pull request.

----------------------------------------------------------------
Lots of cleanups and bug fixes this cycle, primarily in the block
allocation, extent management, fast commit, and journalling.
