Hi,
While taking a look at page_launder()...
/* And re-start the thing.. */ spin_lock(&pagemap_lru_lock); <---------- if (result != 1) continue; /* writepage refused to do anything */ set_page_dirty(page); ^^^^^^^^^^^^^^^^^^^^ goto page_active; }
set_page_dirty() may lock the pagecache_lock which means potential deadlock since we have the pagemap_lru_lock locked.
