--- Comment #24 from SATHEESARAN <sasundar at redhat.com> ---
When this issue was found, it was initally complained that the fuse mount crash
was seen, later through investigation it was found to be 2 seperate problems

1. Crash in FOPs because of integer overflow
2. Sharding doesn't support truncate

Currently the fix addresses only 1. Excerpt from the commit message:
"This patch fixes a crash in FOPs that operate on really large sharded
files where number of participant shards could sometimes exceed
signed int32 max."

But the other issue of sharding to support truncate is not yet available,
which will be tracked with a separate bug.

Based on this, updating the bug summary.
