fs: allocate inode by using alloc_inode_sb()

2022-03-22T22:57:03Z

The inode allocation is supposed to use alloc_inode_sb(), so convert kmem_cache_alloc() of all filesystems to alloc_inode_sb().

fsnotify: fix fsnotify hooks in pseudo filesystems

2022-01-24T13:17:02Z

Commit 49246466a989 ("fsnotify: move fsnotify_nameremove() hook out of d_delete()") moved the fsnotify delete hook before d_delete() so fsnotify will have access to a positive dentry. This allowed a race where opening the deleted file via cached dentry is now possible after receiving the IN_DELETE event. To fix the regression in pseudo filesystems, convert d_delete() calls to d_drop() (see commit 46c46f8df9aa ("devpts_pty_kill(): don't bother with d_delete()") and move the fsnotify hook after d_drop(). Add a missing fsnotify_unlink() hook in nfsdfs that was found during the audit of fsnotify hooks in pseudo filesystems. Note that the fsnotify hooks in simple_recursive_removal() follow d_invalidate(), so they require no change.

sunrpc: destroy rpc_inode_cachep after unregister_filesystem

2020-07-17T17:12:44Z

Better to unregister the file system before destroying the kmem_cache cache of the inodes, so that the inodes are freed before we are trying to destroy it. Otherwise, kmem_cache yells that some objects are live. Signed-off-by: Dan Aloni Signed-off-by: Trond Myklebust

kernel/notifier.c: remove blocking_notifier_chain_cond_register()

2019-12-05T03:44:12Z

blocking_notifier_chain_cond_register() does not consider system_booting state, which is the only difference between this function and blocking_notifier_cain_register(). This can be a bug and is a piece of duplicate code.
