--------------------------------------------
syz-executor120/4217 is trying to acquire lock:
ffff0000e2400100 (&ni->ni_lock){+.+.}-{3:3}, at: ntfs_set_state+0x1a4/0x5c4 fs/ntfs3/fsntfs.c:920

but task is already holding lock:
ffff0000e2407700 (&ni->ni_lock){+.+.}-{3:3}, at: ni_trylock fs/ntfs3/ntfs_fs.h:1123 [inline]
ffff0000e2407700 (&ni->ni_lock){+.+.}-{3:3}, at: ni_write_inode+0x134/0xfb8 fs/ntfs3/frecord.c:3240

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(&ni->ni_lock);
  lock(&ni->ni_lock);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
