+- * If force is CHUNK_ALLOC_FORCE:
++ * Chunk allocation is done in 2 phases:
++ *
++ * 1) Phase 1 - through btrfs_chunk_alloc() we allocate device extents for
++ * the chunk, the chunk mapping, create its block group and add the items
++ * that belong in the chunk btree to it - more specifically, we need to
++ * update device items in the chunk btree and add a new chunk item to it.
++ *
++ * 2) Phase 2 - through btrfs_create_pending_block_groups(), we add the block
++ * group item to the extent btree and the device extent items to the devices
++ * btree.
++ *
++ * This is done to prevent deadlocks. For example when COWing a node from the
++ * extent btree we are holding a write lock on the node's parent and if we
++ * trigger chunk allocation and attempted to insert the new block group item
++ * in the extent btree right way, we could deadlock because the path for the
++ * insertion can include that parent node. At first glance it seems impossible
++ * to trigger chunk allocation after starting a transaction since tasks should
++ * reserve enough transaction units (metadata space), however while that is true
++ * most of the time, chunk allocation may still be triggered for several reasons:
++ *
++ * 1) When reserving metadata, we check if there is enough free space in the
++ * metadata space_info and therefore don't trigger allocation of a new chunk.
++ * However later when the task actually tries to COW an extent buffer from
++ * the extent btree or from the device btree for example, it is forced to
++ * allocate a new block group (chunk) because the only one that had enough
++ * free space was just turned to RO mode by a running scrub for example (or
++ * device replace, block group reclaim thread, etc), so we can not use it
++ * for allocating an extent and end up being forced to allocate a new one;
++ *
++ * 2) Because we only check that the metadata space_info has enough free bytes,
++ * we end up not allocating a new metadata chunk in that case. However if
++ * the filesystem was mounted in degraded mode, none of the existing block
++ * groups might be suitable for extent allocation due to their incompatible
++ * profile (for e.g. mounting a 2 devices filesystem, where all block groups
++ * use a RAID1 profile, in degraded mode using a single device). In this case
++ * when the task attempts to COW some extent buffer of the extent btree for
++ * example, it will trigger allocation of a new metadata block group with a
++ * suitable profile (SINGLE profile in the example of the degraded mount of
++ * the RAID1 filesystem);
++ *
++ * 3) The task has reserved enough transaction units / metadata space, but when
++ * it attempts to COW an extent buffer from the extent or device btree for
++ * example, it does not find any free extent in any metadata block group,
++ * therefore forced to try to allocate a new metadata block group.
++ * This is because some other task allocated all available extents in the
++ * meanwhile - this typically happens with tasks that don't reserve space
++ * properly, either intentionally or as a bug. One example where this is
++ * done intentionally is fsync, as it does not reserve any transaction units
++ * and ends up allocating a variable number of metadata extents for log
++ * tree extent buffers.
++ *
++ * We also need this 2 phases setup when adding a device to a filesystem with
++ * a seed device - we must create new metadata and system chunks without adding
++ * any of the block group items to the chunk, extent and device btrees. If we
++ * did not do it this way, we would get ENOSPC when attempting to update those
++ * btrees, since all the chunks from the seed device are read-only.
++ *
++ * Phase 1 does the updates and insertions to the chunk btree because if we had
++ * it done in phase 2 and have a thundering herd of tasks allocating chunks in
++ * parallel, we risk having too many system chunks allocated by many tasks if
++ * many tasks reach phase 1 without the previous ones completing phase 2. In the
++ * extreme case this leads to exhaustion of the system chunk array in the
++ * superblock. This is easier to trigger if using a btree node/leaf size of 64K
++ * and with RAID filesystems (so we have more device items in the chunk btree).
++ * This has happened before and commit eafa4fd0ad0607 ("btrfs: fix exhaustion of
++ * the system chunk array due to concurrent allocations") provides more details.
++ *
++ * For allocation of system chunks, we defer the updates and insertions into the
++ * chunk btree to phase 2. This is to prevent deadlocks on extent buffers because
++ * if the chunk allocation is triggered while COWing an extent buffer of the
++ * chunk btree, we are holding a lock on the parent of that extent buffer and
++ * doing the chunk btree updates and insertions can require locking that parent.
++ * This is for the very few and rare cases where we update the chunk btree that
++ * are not chunk allocation or chunk removal: adding a device, removing a device
++ * or resizing a device.
++ *
++ * The reservation of system space, done through check_system_chunk(), as well
++ * as all the updates and insertions into the chunk btree must be done while
++ * holding fs_info->chunk_mutex. This is important to guarantee that while COWing
++ * an extent buffer from the chunks btree we never trigger allocation of a new
++ * system chunk, which would result in a deadlock (trying to lock twice an
++ * extent buffer of the chunk btree, first time before triggering the chunk
++ * allocation and the second time during chunk allocation while attempting to
++ * update the chunks btree). The system chunk array is also updated while holding
++ * that mutex. The same logic applies to removing chunks - we must reserve system
++ * space, update the chunk btree and the system chunk array in the superblock
++ * while holding fs_info->chunk_mutex.
++ *
++ * This function, btrfs_chunk_alloc(), belongs to phase 1.
