Subject: [PATCH v6 12/15] xfs: require mmap lock for xfs_break_layouts()
Date: Thu, 15 Mar 2018 08:52:29 -0700 [thread overview]
Message-ID: <152112914933.24669.5543317105428477772.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <152112908134.24669.10222746224538377035.stgit@dwillia2-desk3.amr.corp.intel.com>
In preparation for adding coordination between truncate operations and
busy dax-pages, extend xfs_break_layouts() to assume it must be called
with the mmap lock held. This locking scheme will be required for
coordinating the break of 'dax layouts' (non-idle dax (ZONE_DEVICE)
pages mapped into the file's address space).
