This function is internal to btrfs and doesn't really deal with any VFS members, as such it needn't take a struct inode refrence but btrfs_inode. Signed-off-by:

Currently btrfs_ino takes a struct inode and this causes a lot of internal btrfs functions which consume this ino to take a VFS inode, rather than btrfs' own struct btrfs_inode. In order to fix this "leak" of VFS structs into the internals of btrfs first it's necessary to eliminate all uses of struct inode for the purpose of inode. This patch does that by using BTRFS_I to convert an inode to btrfs_inode. With this problem eliminated subsequent patches will start eliminating the passing of struct inode altogether, eventually resulting in a lot cleaner code. Signed-off-by:

The expression is open-coded in several places, this asks for a wrapper. As we know the MAX_EXTENT fits to u32, we can use the appropirate division helper. This cascades to the result type updates. Compiler is clever enough to use shift instead of integer division, so there's no change in the generated assembly. Signed-off-by: -

A proposed patch in https://marc.info/?l=linux-btrfs&m=147859791003837 pointed out bad limit threshold in cow_file_range_async, but it turned out that the whole logic is not necessary and is done by writeback. We agreed to remove it. Signed-off-by:

As of now writes smaller than 64k for non compressed extents and 16k for compressed extents inside eof are considered as candidate for auto defrag, put them together at a place. Signed-off-by:

Since btrfs_defrag_leaves() does not support extent_root, remove its corresponding call. The user can use the file based defrag to defrag extents as of now. No change in behaviour as extent_root is explicitly skipped in btrfs_defrag_leaves and this has never worked as expected. Signed-off-by:

btrfs_add_delayed_data_ref is always called with a NULL extent_op, so let's drop the argument. Signed-off-by:

The check for a null inode is redundant since the function is a callback for exportfs, which will itself crash if dentry->d_inode or parent->d_inode is NULL. Removing the null check makes this consistent with other file systems. Also remove the redundant null dir check too. Found with static analysis by CoverityScan, CID 1389472 Kudos to Jeff Mahoney for reviewing and explaining the error in my original patch (most of this explanation went into the above commit message) and David Sterba for pointing out that the dir check is also redundant.

This cleans up the cases where the min/max macros were used with a cast rather than using directly min_t/max_t. Signed-off-by:

try_release_extent_state reduces the gfp mask to GFP_NOFS if it is compatible. This is true for GFP_KERNEL as well. There is no real reason to do that though. There is no new lock taken down the the only consumer of the gfp mask which is try_release_extent_state clear_extent_bit __clear_extent_bit alloc_extent_state So this seems just unnecessary and confusing.

b335b003 ("Btrfs: Avoid using __GFP_HIGHMEM with slab allocator") has reduced the allocation mask in btrfs_releasepage to GFP_NOFS just to prevent from giving an unappropriate gfp mask to the slab allocator deeper down the callchain (in alloc_extent_state). This is wrong for two reasons a) GFP_NOFS might be just too restrictive for the calling context b) it is better to tweak the gfp mask down when it needs that. So just remove the mask tweaking from btrfs_releasepage and move it down to alloc_extent_state where it is needed. Signed-off-by:

Goldwyn Rodrigues has exposed and fixed a bug which underflows btrfs qgroup reserved space, and leads to non-writable fs. This reminds us that we don't have enough underflow check for qgroup reserved space. For underflow case, we should not really underflow the numbers but warn and keeps qgroup still work. So add more check on qgroup reserved space and add WARN_ON() and btrfs_warn() for any underflow case. Signed-off-by:
