We know that eadpage_end_io_hook, submit_bio_hook and merge_bio_hook are always defined so we can drop the checks before we call them. Signed-off-by:David Sterba <dsterba@suse.com>

Some of the callbacks defined in btree_extent_io_ops and btrfs_extent_io_ops do always exist so we don't need to check the existence before each call. This patch just reorders the definition and documents which are mandatory/optional. Signed-off-by: -

The space check in btrfs_insert_xattr_item is duplicated in it's caller (do_setxattr) so we won't hit the BUG_ON. Continuing without any check could be disasterous so turn it to a proper error handling. Reviewed-by:

All callers dereference the 'tm' parameter before it gets to this function, the NULL check does not make much sense here. Reviewed-by:

The value of max_out can be calculated from the parameters passed to the compressors, which is number of pages and the page size, and we don't have to needlessly pass it around. Signed-off-by: -

The parameter saying how many pages can be allocated at maximum can be merged with the output page counter, to save some stack space. The compression implementation will sink the parameter to a local variable so everything works as before. The nr_pages variables can also be simply merged in compress_file_range into one.

The length parameter is basically duplicated for input and output in the top level caller of the compress_pages chain. We can simply use one variable for that and reduce stack consumption. The compression implementation will sink the parameter to a local variable so everything works as before. Signed-off-by: -

The function does not modify the input buffer, also update a typecast in one caller. Signed-off-by: -

In addition to changing the signature, this patch also switches all the functions which are used as an argument to also take btrfs_inode. Namely those are: btrfs_get_extent and btrfs_get_extent_filemap. Signed-off-by:
