We just upgraded and I noticed ldiskfs doesn't build. Are you seeing this too?

Hi James,
Could you please try the above patch?

Comment by James A Simmons [ 17/Sep/20 ]

Do we need the LU-13300 work for this RHEL version?

Comment by Jian Yu [ 17/Sep/20 ]

No, James.
The extent status tree shrinker patches are removed from the RHEL 7.8 kernel patch series because the following bug fix has been included since version 3.10.0-1127.18.2.el7:

ext4: change LRU to round-robin in extent status tree shrinker (BZ#1847343)
