[PATCH] btrfs: Ensure replaced device doesn't have pending chunk allocation

by Nikolay Borisov

Recent FITRIM work, namely bbbf7243d62d ("btrfs: combine device update operations during transaction commit") combined the way certain operations are recoded in a transaction. As a result an ASSERT was added in dev_replace_finish to ensure the new code works correctly. Unfortunately I got reports that it's possible to trigger the assert, meaning that during a device replace it's possible to have an unfinished chunk allocation on the source device. This is supposed to be prevented by the fact that a transaction is committed before finishing the replace oepration and alter acquiring the chunk mutex. This is not sufficient since by the time the transaction is committed and the chunk mutex acquired it's possible to allocate a chunk depending on the workload being executed on the replaced device. This bug has been present ever since device replace was introduced but there was never code which checks for it. The correct way to fix is to ensure that there is no pending device modification operation when the chunk mutex is acquire and if there is repeat transaction commit. Unfortunately it's not possible to just exclude the source device from btrfs_fs_devices::dev_alloc_list since this causes ENOSPC to be hit in transaction commit. Fixing that in another way would need to add special cases to handle the last writes and forbid new ones. The looped transaction fix is more obvious, and can be easily backported. The runtime of dev-replace is long so there's no noticeable delay caused by that.

When it happened that one process was mapping file at PMD granularity while another process at PTE granularity, we could wrongly deassociate PMD range and then reassociate PTE range leaving the rest of struct pages in PMD range without mapping information which could later cause missed notifications about memory errors. Fix the problem by calling the association / deassociation code if and only if we are really going to update the xarray (deassociating and associating zero or empty entries is just no-op so there's no reason to complicate the code with trying to avoid the calls for these cases).

[PATCH] dmaengine: qcom: bam_dma: Fix completed descriptors count

by Sricharan R

One space is left unused in circular FIFO to differentiate 'full' and 'empty' cases. So take that in to account while counting for the descriptors completed.
