[fuse-devel] How to determine release of file writer

[Peter R. <pet...@di...>]

I have an implementation of a fuse userSpace file system that requires
some processing to be done whenever the writer of a file closes the
file. I was using the RELEASE operation to trigger this, but now I need
to refine my approach and do the operation only once and only when the
writer process closes the file not just whenever any process releases
the file. Can anyone suggest a good approach to doing this?

Also, I have noticed that when I copy files from elsewhere to my mounted
fuse file system that I get only blocks of 4096 bytes each time to write
to the destination. What controls the block size that my user space file
system gets, and how can I set things up to get larger data blocks at a
time? The data files that I am dealing with are usually quite large and
it would seem that working with larger blocks should help improve the
system performance.

Thanks for any help you can give me.
