Description:
Writeback for filesystems is the process of flushing the "dirty" (written)
data in the page cache to storage. At
the 2025 Linux Storage,
Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Anuj Gupta led a combined storage and filesystem session on some work that has been done
to parallelize the writeback process. Some of the performance problems
that have been seen with the existing single-threaded writeback came up in
a session at last year's summit , where the
idea of doing writeback in parallel was discussed.
