There is a AB-BA deadlock regarding drop_caches sysctl. Here are the code
paths:
drop_pagecache
spin_lock(&inode_lock);
invalidate_mapping_pages
try_to_release_page
ext3_releasepage
journal_try_to_free_buffers
__journal_try_to_free_buffer
spin_lock(&jour
There is a AB-BA deadlock regarding drop_caches sysctl. Here are the code
