New Patches Optimize EXT4 Online Defragmentation For Better Performance
A set of 13 patches were posted today to the Linux kernel mailing list for optimizing the online defragmentation handling by the EXT4 kernel driver
Huawei engineer Zhang Yi posted the patches to the Linux kernel mailing list for improving the EXT4 file-system online defragmentation handling. Additionally, the current implementation is tightly coupled with buffer_head, making it unable to support after the conversion of buffered I/O processes to the iomap infrastructure. Additionally, the primary objective of this set of patches is to prepare for converting the buffered I/O process for regular files to the iomap infrastructure.
