2024-02-05ARM: dts: imx6ull-dhcor: Remove 900MHz operating pointChristoph Niedermaier
Due to CPU lifetime consideration of the SoC manufacturer [1] and the preferred area of operation in the industrial related environment, set the maximum frequency for each DHCOM i.MX6ULL to 792MHz, as with the industrial type. This is done by removing the operating point at 900MHz and set the clock-frequency to 792000000.

2024-01-21bcachefs: Prep work for variable size btree node buffersKent Overstreet
bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate.

There is a comment "why do we need this lock?" about the lock coming from commit 42d237320e98 ("bcachefs: Snapshot creation, deletion") The reason is that __bch2_ioctl_subvolume_create() calls sync_inodes_sb() which enforce locked s_umount to writeback all dirty nodes before doing snapshot works. Fix it by read locking s_umount for snapshotting only and unlocking s_umount after sync_inodes_sb().
