    ext4: make xattr inode reads faster · 9699d4f9
    Tahsin Erdogan authored
    ext4_xattr_inode_read() currently reads each block sequentially while
    waiting for io operation to complete before moving on to the next
    block. This prevents request merging in block layer.
    
    Add a ext4_bread_batch() function that starts reads for all blocks
    then optionally waits for them to complete. A similar logic is used
    in ext4_find_entry(), so update that code to use the new function.
