[$] The Linux "copy problem"

<p>In a filesystem session on the third day of the 2019 Linux Storage,Filesystem, and Memory-Management Summit (LSFMM), Steve French wanted totalk about copy operations. Much of the development work that has gone onin the Linux filesystem world over the last few years has been related tothe performance ofcopying files, at least indirectly, he said. There are still painpoints around copy operations, however, so he would like to see those getaddressed.
