This function always takes a transaction handle which references the fs_info structure. So use that and remove the extra argument. Signed-off-by:

Currently when checking if a directory can be deleted, we always check if all its children have been processed. Example: A directory with 2,000,000 files was deleted original: 1994m57.071s patch: 1m38.554s [FIX] Instead of checking all children on all calls to can_rmdir(), we keep track of the directory index offset of the child last checked in the last call to can_rmdir(), and then use it as the starting point for future calls to can_rmdir().

add_delayed_ref_head really performed 2 independent operations - initialisting the ref head and adding it to a list. Now that the init part is in a separate function let's complete the separation between both operations. This results in a lot simpler interface for add_delayed_ref_head since the function now deals solely with either adding the newly initialised delayed ref head or merging it into an existing delayed ref head. This results in vastly simplified function signature since 5 arguments are dropped. The only other thing worth mentioning is that due to this split the WARN_ON catching reinit of existing. In this patch the condition is extended such that: qrecord && head_ref->qgroup_ref_root && head_ref->qgroup_reserved is added. This is done because the two qgroup_* prefixed member are set only if both ref_root and reserved are passed. So functionally it's equivalent to the old WARN_ON and allows to remove the two args from add_delayed_ref_head. Signed-off-by:

Use the newly introduced function when initialising the head_ref in add_delayed_ref_head. No functional changes. Signed-off-by:

Nikolay Borisov authored
add_delayed_ref_head implements the logic to both initialize a head_ref structure as well as perform the necessary operations to add it to the delayed ref machinery. This has resulted in a very cumebrsome interface with loads of parameters and code, which at first glance, looks very unwieldy. Begin untangling it by first extracting the initialization only code in its own function. It's more or less verbatim copy of the first part of add_delayed_ref_head. Signed-off-by:

Now that the initialization part and the critical section code have been split it's a lot easier to open code add_delayed_data_ref. Do so in the following manner: 1. The common init function is put immediately after memory-to-be-initialized is allocated, followed by the specific data ref initialization. 2. The only piece of code that remains in the critical section is insert_delayed_ref call. 3. Tracing and memory freeing code is moved outside of the critical section. No functional changes, just an overall shorter critical section. Signed-off-by:

Now that the initialization part and the critical section code have been split it's a lot easier to open code add_delayed_tree_ref. Do so in the following manner: 1. The comming init code is put immediately after memory-to-be-initialized is allocated, followed by the ref-specific member initialization. 2. The only piece of code that remains in the critical section is insert_delayed_ref call. 3. Tracing and memory freeing code is put outside of the critical section as well. The only real change here is an overall shorter critical section when dealing with delayed tree refs. From functional point of view - the code is unchanged. Signed-off-by:

THe majority of the init code for struct btrfs_delayed_ref_node is duplicated in add_delayed_data_ref and add_delayed_tree_ref. Factor out the common bits in init_delayed_ref_common. This function is going to be used in future patches to clean that up. No functional changes. Signed-off-by:

When debugging quota rescan race, some times btrfs rescan could account some old (committed) leaf and then re-account newly committed leaf in next generation. This race needs extra transid to locate, so add @transid for trace_btrfs_qgroup_account_extent() for such debug. Signed-off-by:

Origin trace_qgroup_update_counters() only records qgroup id and its reference count change. It's good enough to debug qgroup accounting change, but when rescan race is involved, it's pretty hard to distinguish which modification belongs to which rescan. So add old_rfer and old_excl trace output to help distinguishing different rescan instance. (Different rescan instance should reset its qgroup->rfer to 0) For trace event parameter, it just changes from u64 qgroup_id to struct btrfs_qgroup *qgroup, so number of parameters is not changed at all.

It's used only in inode.c so makes no sense to have it exported. Also move the definition of btrfs_delalloc_work to inode.c since it's used only this file. Signed-off-by:

When allocating a delalloc work we are always setting the delayed_iput to 0. So remove the delay_iput member of btrfs_delalloc_work, as a result also remove it as a parameter from btrfs_alloc_delalloc_work since it's not used anymore. Signed-off-by:

This parameter was introduced alongside the function in eb73c1b7 ("Btrfs: introduce per-subvolume delalloc inode list") to avoid deadlocks since this function was used in the transaction commit path. However, commit 8d875f95 ("btrfs: disable strict file flushes for renames and truncates") removed that usage, rendering the parameter obsolete. Signed-off-by:

In btrfs_shrink_device, before btrfs_search_slot, path->reada is set to READA_FORWARD. But I think READA_BACK is correct. Since: 1. key.offset is set to (u64)-1 2. after btrfs_search_slot, btrfs_previous_item is called So, for readahead previous items, READA_BACK is the correct one. Signed-off-by:

This patch will add the following trace events: 1) btrfs_remove_block_group For btrfs_remove_block_group() function. Triggered when a block group is really removed. 2) btrfs_add_unused_block_group Triggered which block group is added to unused_bgs list. 3) btrfs_skip_unused_block_group Triggered which unused block group is not deleted. These trace events is pretty handy to debug case related to block group auto remove. Signed-off-by:
