      [PATCH] fuse: fix async read for legacy filesystems · 9cd68455
      Miklos Szeredi 提交于
      While asynchronous reads mean a performance improvement in most cases, if
      the filesystem assumed that reads are synchronous, then async reads may
      degrade performance (filesystem may receive reads out of order, which can
      confuse it's own readahead logic).
      
      With sshfs a 1.5 to 4 times slowdown can be measured.
      
      There's also a need for userspace filesystems to know whether asynchronous
      reads are supported by the kernel or not.
      
      To achive these, negotiate in the INIT request whether async reads will be
      used and the maximum readahead value.  Update interface version to 7.6
      
      If userspace uses a version earlier than 7.6, then disable async reads, and
      set maximum readahead value to the maximum read size, as done in previous
      versions.
