Hi. Richard
Just a reminding. Could you please look through following series(Some of them is sent several months ago), I wish these can be merged in 6.1, thanks a lot:

ubi infinite loop: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=304485
ubi uaf in sysfs: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=311956
ubi fastmap: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=313063
ubifs assertion failed about writepage: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=302776
ubifs space budget: https://patchwork.ozlabs.org/project/linux-mtd/list/?series=322220

This series of patches fix ubifs wrong budget space calculations,
which could make make_reservation() failed with ENOSPC error code
and let ubifs become read-only.

Zhihao Cheng (6):
ubifs: Rectify space budget for ubifs_symlink() if symlink is
encrypted
ubifs: Rectify space budget for ubifs_xrename()
ubifs: Add comments and debug info for ubifs_xrename()
ubifs: Fix wrong dirty space budget for dirty inode
ubifs: do_rename: Fix wrong space budget when target inode's nlink > 1
ubifs: Reserve one leb for each journal head while doing budget
