Date: Mon Aug 17 15:36:15 2020 +0800 - - ext4: limit the length of per-inode prealloc list - - In the scenario of writing sparse files, the per-inode prealloc list may - be very long, resulting in high overhead for ext4_mb_use_preallocated(). - To circumvent this problem, we limit the maximum length of per-inode - prealloc list to 512 and allow users to modify it. - - After patching, we observed that the sys ratio of cpu has dropped, and - the system throughput has increased significantly.
