* Copy a range of data from one file to anotherNiels de Vos, 4 years ago: • libfuse: add copy_file_range() support

*
|
|
* Performs an optimized copy between two file descriptors without the
|
|
* additional cost of transferring data through the FUSE kernel module
|
|
* to user space (glibc) and then back into the FUSE filesystem again.
|
|
*
|
|
* In case this method is not implemented, applications are expected to
|
|
* fall back to a regular file copy. (Some glibc versions did this
|
|
* emulation automatically, but the emulation has been removed from all
|
|
* glibc release branches.)
