None of the checks need to know the ro/rw status as they're all not changing the superblock. Moreover, we can access the sb flags directly if we'd need to decide by the ro/rw status. Reviewed-by:

There was never need for RCU protection around reading nodesize or other fairly constant filesystem data. Signed-off-by: -

The helper name is not too helpful and is just wrapping a simple call. Signed-off-by: -

The quota status used to be tracked as a variable, so the mutex was needed (until "Btrfs: add a flags field to btrfs_fs_info" afcdd129). Since the status is a bit modified atomically and we don't hold the mutex beyond the check, we can drop it. Signed-off-by:

Status of quotas should be the first check in btrfs_qgroup_account_extent and we can return immediatelly, no need to do no-op ulist frees. Signed-off-by: -
David Sterba authored
We can embed range_changed to the extent changeset to address following problems: - no need to allocate ulist dynamically, we also get rid of the GFP_NOFS for free - fix lack of allocation failure checking in btrfs_qgroup_reserve_data The stack consuption where extent_changeset is used slightly increases: before: 16 after: 16 - 8 (for pointer) + 32 (sizeof ulist) = 40 Which is bearable.

We do a readahead of the free space cache inode to speed things up but the failure is not fatal, like in other readahead cases. Proper reads would need to happen anyway and any errors would be caught there. Reviewed-by:

Qgroup relations are added/deleted from ioctl, we hold the high level qgroup lock, no deadlocks or recursion from the allocation possible here. Signed-off-by: -
David Sterba authored
We don't need to use GFP_NOFS here as this is called from ioctls an the only lock held is the subvol_sem, which is of a high level and protects creation/renames/deletion and is never held in the writeout paths. Signed-off-by:
