选项:no_heap 影响:禁用 heap-based 分配可以减少内存碎片,提高写入性能。 inline_data: 描述:将小文件的数据内联存储。 选项:inline_data 影响:对于小文件,内联存储可以减少 I/O 操作,提高写入性能。 fsync_mode: 描述:控制 fsync() 调用的行为。 选项:barrier(默认)、nobarrier、none 影响:nobarrier和none可以...
- fsync_mode:指定fsync()调用的行为。可以是以下三个值之一: - barrier(默认):使用barrier命令确保数据写入闪存。 - nobarrier:不使用barrier命令,以提高性能。 - none:完全禁用fsync()调用,可能会导致数据丢失。 - discard:启用TRIM命令,用于释放删除文件后的闪存块。 - no_heap:禁用堆管理器,使用连续的闪存块...

nobarrier This option can be used if underlying storage guarantees its cached data should be written to the novolatile area. If this option is set, no cache_flush commands are issued but f2fs still guarantees the write ordering of all the data writes. fastboot This option is used when a ...
