From 6866d7b3f2bb4f011041ba54c98b1584497fe2fd Mon Sep 17 00:00:00 2001 From: Harshad Shirwadkar Date: Thu, 15 Oct 2020 13:37:55 -0700 Subject: ext4 / jbd2: add fast commit initialization This patch adds fast commit area trackers in the journal_t structure. These are initialized via the jbd2_fc_init() routine that this patch adds. This patch also adds ext4/fast_commit.c and ext4/fast_commit.h files for fast commit code that will be added in subsequent patches in this series.
