The API changes from: int nbd_add_close_callback (struct nbd_handle *h, nbd_close_callback cb, void *user_data); to: int nbd_add_close_callback (struct nbd_handle *h, void *user_data, nbd_close_callback cb); The second way is consistent with how other callbacks work

Hi Chris, this serie of patches updated the command "btrfs filesystem df". I update this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show". This patch was the result of some discussions on the btrfs mailing list. Many thanks to all the contributors. From the man page (see 2nd patch): [...] The

Existing practice tends to prefer the void* closure argument for C callbacks to occur after the function pointer (POSIX: pthread_create; glibc: qsort_r; glib: g_thread_new; libvirt: virConnectDomainEventRegisterAny; etc.). It's also handy to think that calling 'myfunc(cb, arg)' will eventually result in a call to 'cb(arg)'. While I couldn't quickly find any style guide

In preparation for closure lifetimes, split up the Closure so it no longer describes a list of closures, but a single callback. This changes the API because functions which take 2 or more closures now pass a separate user_data for each one. --- docs/libnbd.pod | 3 +- examples/strict-structured-reads.c | 2 +- generator/generator | 760
