[fuse-devel] normal file close vs file close upon process fault

[Gerard J. C. <gj...@ci...>]

I am not sure there is a solution for this but if anyone has an idea I 
would be eager to test it out.

Being that I am building a WORM file system that buffers all data before 
commitment and then commits only on file close, I am wondering if I can 
detect if the flush and release occurred because the writing application 
came to an uneventful completion or suffered an untimely demise such as 
a segmentation fault.

In other words, I want to detect the situation where the OS is closing 
up the open files after killing a wayward process rather than the 
process finishing its work and closing the files.

I wrote a little Kamikaze process and, indeed, the partially written 
file is committed by the OS.

Any Ideas?
