[RESEND PATCH v3 1/2] fs/buffer: clean up block_commit_write

From: Bean Huo
Date: Mon Jun 26 2023 - 01:55:44 EST


From: Bean Huo <beanhuo@xxxxxxxxxx>

Originally inode is used to get blksize, after commit 45bce8f3e343
("fs/buffer.c: make block-size be per-page and protected by the page lock"),
__block_commit_write no longer uses this parameter inode.
