Subject: [PATCH 11/16] fuse2fs: fix default acls propagating to non-dir children
Date: Thu, 16 Oct 2025 08:42:40 -0700	[thread overview]
Message-ID: <176062915665.3343688.5505234672337035445.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <176062915393.3343688.9810444125172113159.stgit@frogsfrogsfrogs>

From: Darrick J. Wong <djwong@kernel.org>

New non-directory children should not be copying the default ACLs of the
parents.  Caught by generic/099 in fuseblk/iomap mode.

Cc: <linux-ext4@vger.kernel.org> # v1.47.3
Fixes: 2c7900387620a6 ("fuse2fs: propagate default ACLs to new children")
