In a filesystem session on the third day of the 2019 Linux Storage,
Filesystem, and Memory-Management Summit (LSFMM), Steve French wanted to
talk about copy operations. Much of the development work that has gone on
in the Linux filesystem world over the last few years has been related to
the performance of
copying files, at least indirectly, he said. There are still pain
points around copy operations, however, so he would like to see those get
addressed.
