2024-02-05remoteproc: k3-dsp: Use devm_ti_sci_get_by_phandle() helperAndrew Davis1-23/+9
Use the device lifecycle managed TI-SCI get() function. This helps prevent mistakes like not put()'ing in the wrong order in cleanup functions and forgetting to put() on error paths.

2024-01-21bcachefs: Prep work for variable size btree node buffersKent Overstreet18-97/+87
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.

The variable tmp is being assigned a value but it isn't being read afterwards. The assignment is redundant and so tmp can be removed.

2024-01-21bcachefs: Fix excess transaction restarts in __bchfs_fallocate()Kent Overstreet4-16/+35
drop_locks_do() should not be used in a fastpath without first trying the do in nonblocking mode - the unlock and relock will cause excessive transaction restarts and potentially livelocking with other threads that are contending for the same locks.

2024-01-21bcachefs: Better journal tracepointsKent Overstreet2-60/+79
Factor out bch2_journal_bufs_to_text(), and use it in the journal_entry_full() tracepoint; when we can't get a journal reservation we need to know the outstanding journal entry sizes to know if the problem is due to excessive flushing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2024-01-21bcachefs: Avoid flushing the journal in the discard pathKent Overstreet1-19/+41
When issuing discards, we may need to flush the journal if there's too many buckets that can't be discarded until a journal flush. But the heuristic was bad; we should be comparing the number of buckets that need to flushes against the number of free buckets, not the number of buckets we saw.

2024-01-21bcachefs: bch2_kthread_io_clock_wait() no longer sleeps until full amountKent Overstreet1-2/+2
Drop t he loop in bch2_kthread_io_clock_wait(): this allows the code that uses it to be woken up for other reasons, and fixes a bug where rebalance wouldn't wake up when a scan was requested. This raises the possibility of spurious wakeups, but callers should always be able to handle that reasonably well. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
