err holds the return value of either btrfs_del_root_ref() or
btrfs_del_inode_ref() but it hasn't been checked since it's
introduction with commit fe66a05a0679 (Btrfs: improve error handling
for btrfs_insert_dir_item callers) in 2012.
Instead of silently ignoring the return values, print a message
The btrfs_bio_end_io_t typedef was introduced with commit
a1d3c4786a4b ("btrfs: btrfs_multi_bio replaced with btrfs_bio")
but never used anywhere. This commit also introduced a forward declaration
of 'struct btrfs_bio' which is only needed for btrfs_bio_end_io_t.
Remove both as they're not needed

Will capture all of that this evening, and try it with the latest
kernel and tools. Thanks for the input on what info is relevant, with
gather it asap.

Changed subject to better match what we discuss and added btrfs list to CC.

When a transaction commit starts, it attempts to pause scrub and it blocks
until the scrub is paused. So while the transaction is blocked waiting for
scrub to pause, we can not do memory allocation with GFP_KERNEL while scrub
is running, we must use GFP_NOS to avoid deadlock w

The function relocate_block_group calls btrfs_end_transaction to release
trans when update_backref_cache returns 1, and then continues the loop
body. If btrfs_block_rsv_refill fails this time, it will jump out the
loop and the freed trans will be accessed. This may result in a
use-after-free bug. T
