dax: skip read lock assertion for read-only filesystems
[ Upstream commit 154d1e7ad9e5ce4b2aaefd3862b3dba545ad978d ]
The commit 168316db3583("dax: assert that i_rwsem is held
exclusive for writes") added lock assertions to ensure proper
locking in DAX operations. However, these assertions trigger
false-positive lockdep warnings since read lock is unnecessary
on read-only filesystems(e.g., erofs).
This patch skips the read lock assertion for read-only filesystems,
eliminating the spurious warnings while maintaining the integrity
checks for writable filesystems.
Fixes: 168316db3583 ("dax: assert that i_rwsem is held exclusive for writes")
