From: "Ritesh Harjani (IBM)" <ritesh.list@gmail.com> mainline inclusion from mainline-v6.15-rc4 commit 255e7bc2127cbd3a718a55d2da5b2d3f015adcd7 category: feature bugzilla: https://atomgit.com/src-openeuler/kernel/issues/8862 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- Let's make ext4_meta_trans_blocks() non-static for use in later functions during ->end_io conversion for atomic writes. We will need this function to estimate journal credits for a special case. Instead of adding another wrapper around it, let's make this non-static.
