[issue27879] add os.syncfs()

[Nir Soffer]

Nir Soffer  added the comment:

Updating python version, this is not relevant to 3.6 now.

On linux users can use "sync --file-system /path" but it would be nice if we 
have something that works on multiple platforms.

1. It is appropriate to call `sync()` when one calls `os.syncfs()` if 
`syncfs()` syscall is not supported in kernel.

[issue27879] add os.syncfs()

[Josh Rosenberg]

Josh Rosenberg added the comment:

So syncfs is basically "sync, but only for a single file system corresponding 
to a given open file"? Given it's Linux only (doesn't look like it's part of 
any standard that UNIX or BSD OSes would provide), it seems rather special 
purpose to expose in Python. Is there some equivalent API for UNIX/BSD variants 
that `syncfs` could use to provide a single API that works on at least all 
UNIX-like systems? If not, it seems like this is an optimization that doesn't 
generalize; is it worth providing it instead of just having users call os.sync 
and accepting the cost of syncing other file systems?
