Subject: potential race in FUSE's readdir() + releasedir()?
Date: Sun, 03 Jul 2022 15:36:42 +0100	[thread overview]
Message-ID: <87tu7yjm9x.fsf@vostro.rath.org> (raw)

Hello,

I am seeing something that to me looks like a race between FUSE's
readdir() and releasedir() handlers. On kernel 5.18, the FUSE daemon
seems to (ocasionally) receive a releasedir() request while a readdir()
request with the same `struct fuse_file_info *fi->fh` is still active
(i.e., the FUSE daemon hasn't sent a reply to the kernel for this yet).

Could this be a bug in the kernel? Or is there something else that could
explain this?

Best,
-Nikolaus
