I backported the following patches for the LU-16637 on the b2_15 branch (2.15.6):

- LU-16637 llite: tolerate fresh page cache pages after truncate
- LU-16958 llite: migrate vs regular ops deadlock
- LU-16637 llite: call truncate_inode_pages() in inode lock
- LU-16637 llite: call truncate_inode_pages() under inode lock

This is to prepare the next custom release of Lustre 2.15.6 for the CEA.

You can try to build and test the following branch to see if it fixes your issue: https://review.whamcloud.com/57655
git fetch "https://review.whamcloud.com/fs/lustre-release" refs/changes/55/57655/1 && git checkout -b LU-16637_2.15FETCH_HEAD
