Subject: [PATCH 0/2] fuse: Fix possible memleak at startup with immediate teardown
Date: Tue, 21 Oct 2025 23:33:29 +0200 [thread overview]
Message-ID: <20251021-io-uring-fixes-cancel-mem-leak-v1-0-26b78b2c973c@ddn.com> (raw)
Do not merge yet, the current series has not been tested yet.
The race is only easily reproducible with additional patches that
pin pages during FUSE_IO_URING_CMD_REGISTER - slows it down and then
xfstest's generic/001 triggers it reliably. However, I need to update
these pin patches for linux master.
