Hi.
The zfs_path_to_zhandle() function was recently added to libzfs and I'm
trying to figure out how it works by reading the code.
/*
* Given a name, determine whether or not it's a valid path
* (starts with '/' or "./"). If so, walk the mnttab trying
* to match the device number. If not, treat the path as an
* fs/vol/snap name.
*/
[...]
while ((ret = getextmntent(hdl->libzfs_mnttab, &entry, 0)) == 0) {
if (makedevice(entry.mnt_major, entry.mnt_minor) ==
statbuf.st_dev) {
What device are we looking here for? ZFS file systems are not based on
raw device, right? What does mnt_major and mnt_minor here mean exactly?
I thought that those are numbers of device from which file system is
mounted.
Can someone give me an example of how this code path is used?
zfs list /<what?>
