FUSE Improvements Merged For Linux 6.16 To Enhance File-Systems In User-Space

([Linux Storage] 6 Hours Ago Linux 6.16 FUSE)


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 [1]yield a nice performance gain for FUSE file-systems .

More details on the FUSE changes for this next version of the Linux kernel via [2]this pull request that has since been merged to Git.
