2024-09-21clk: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all clk drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-09-21bcachefs: Hold read lock in bch2_snapshot_tree_oldest_subvol()Ahmed Ehab
Syzbot reports a problem that a warning is triggered due to suspicious use of rcu_dereference_check(). That is triggered by a call of bch2_snapshot_tree_oldest_subvol(). The cause of the warning is that inside bch2_snapshot_tree_oldest_subvol(), snapshot_t() is called which calls rcu_dereference() that requires a read lock to be held. Also, the call of bch2_snapshot_tree_next() eventually calls snapshot_t(). To fix this, call rcu_read_lock() before calling snapshot_t(). Then, release the lock after the termination of the while loop.

2024-09-21bcachefs: Rework btree node pinningKent Overstreet
In backpointers fsck, we do a seqential scan of one btree, and check references to another: extents <-> backpointers Checking references generates random lookups, so we want to pin that btree in memory (or only a range, if it doesn't fit in ram). Previously, this was done with a simple check in the shrinker - "if btree node is in range being pinned, don't free it" - but this generated OOMs, as our shrinker wasn't well behaved if there was less memory available than expected. Instead, we now have two different shrinkers and lru lists; the second shrinker being for pinned nodes, with seeks set much higher than normal - so they can still be freed if necessary, but we'll prefer not to.

2024-09-21bcachefs: Options for recovery_passes, recovery_passes_excludeKent Overstreet
This adds mount options for specifying recovery passes to run, or exclude; the immediate need for this is that backpointers fsck is having trouble completing, so we need a way to skip it. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: Use mm_account_reclaimed_pages() when freeing btree nodesKent Overstreet
When freeing in a shrinker callback, we need to notify memory reclaim, so it knows forward progress has been made. Normally this is done in e.g. slab code, but we're not freeing through slab - or rather we are, but these allocations are big, and use the kmalloc_large() path. This is really a bug in the slub code, but we're working around it here for now. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-09-21bcachefs: rebalance writes use BCH_WRITE_ONLY_SPECIFIED_DEVSKent Overstreet
this was an oversight: rebalance is moving data to a specific device, so we don't want it falling back to the full filesystem Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-09-21bcachefs: BCH_WRITE_ALLOC_NOWAIT no longer applies to open bucket allocationKent Overstreet
rebalance writes must be BCH_WRITE_ALLOC_NOWAIT because they don't allocate from the full filesystem - but we don't want spurious allocation failures due to open buckets. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-09-21bcachefs: convert __bch2_encrypt_bio() to darrayKent Overstreet
like the previous patch, kill use of bare arrays; the encryption code likes to work in big batches, so this is a small performance improvement. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull non-MM updates from Andrew Morton: "Many singleton patches - please see the various changelogs for details. Quite a lot of nilfs2 work this time around. Notable patch series in this pull request are: - "mul_u64_u64_div_u64: new implementation" by Nicolas Pitre, with assistance from Uwe Kleine-König. Reimplement mul_u64_u64_div_u64() to provide (much) more accurate results. The current implementation was causing Uwe some issues in the PWM drivers. - "xz: Updates to license, filters, and compression options" from Lasse Collin. Miscellaneous maintenance and kinor feature work to the xz decompressor. - "Fix some GDB command error and add some GDB commands" from Kuan-Ying Lee. Fixes and enhancements to the gdb scripts. - "treewide: add missing MODULE_DESCRIPTION() macros" from Jeff Johnson. Adds lots of MODULE_DESCRIPTIONs, thus fixing lots of warnings about this. - "nilfs2: add support for some common ioctls" from Ryusuke Konishi. Adds various commonly-available ioctls to nilfs2. - "This series fixes a number of formatting issues in kernel doc comments" from Ryusuke Konishi does that. - "nilfs2: prevent unexpected ENOENT propagation" from Ryusuke Konishi. Fix issues where -ENOENT was being unintentionally and inappropriately returned to userspace. - "nilfs2: assorted cleanups" from Huang Xiaojia. - "nilfs2: fix potential issues with empty b-tree nodes" from Ryusuke Konishi fixes some issues which can occur on corrupted nilfs2 filesystems. - "scripts/decode_stacktrace.sh: improve error reporting and usability" from Luca Ceresoli does those things" * tag 'mm-nonmm-stable-2024-09-21-07-52' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (103 commits) list: test: increase coverage of list_test_list_replace*() list: test: fix tests for list_cut_position() proc: use __auto_type more treewide: correct the typo 'retun' ocfs2: cleanup return value and mlog in ocfs2_global_read_info() nilfs2: remove duplicate 'unlikely()' usage nilfs2: fix potential oob read in nilfs_btree_check_delete() nilfs2: determine empty node blocks as corrupted nilfs2: fix potential null-ptr-deref in nilfs_btree_insert() user_namespace: use kmemdup_array() instead of kmemdup() for multiple allocation tools/mm: rm thp_swap_allocator_test when make clean squashfs: fix percpu address space issues in decompressor_multi_percpu.c lib: glob.c: added null check for character class nilfs2: refactor nilfs_segctor_thread() nilfs2: use kthread_create and kthread_stop for the log writer thread nilfs2: remove sc_timer_task nilfs2: do not repair reserved inode bitmap in nilfs_new_inode() nilfs2: eliminate the shared counter and spinlock for i_generation nilfs2: separate inode type information from i_state field nilfs2: use the BITS_PER_LONG macro ...
