FUSE Improvements Merged For Linux 6.16 To Enhance File-Systems In User-Space
The FUSE improvements have been merged for the Linux 6.16 in enhancing the capabilities for file-systems implemented in user-space.
FUSE in Linux 6.16 removes the temporary page copying in the writeback code path. In turn this nets a nice reduction in the number of lines of code as well as reducing complexity for FUSE implementations. FUSE also converted more code over to handling large folios, atomic cache lookup invalidation, optimizing the IO_uring request expiration, and other fixes/improvements.
Arguably the most notable change for end-users for FUSE in Linux 6.16 is increasing the read directory "readdir" buffer size. In turn this larger buffer size can yield a nice performance gain for FUSE file-systems.
