Subject: [PATCH AUTOSEL 5.15 01/20] fs/ntfs3: Fix work with fragmented xattr
Date: Wed, 24 Aug 2022 21:36:53 -0400 [thread overview]
Message-ID: <20220825013713.22656-1-sashal@kernel.org> (raw)
From: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
[ Upstream commit 42f86b1226a42bfc79a7125af435432ad4680a32 ]
In some cases xattr is too fragmented,
so we need to load it before writing.
