4a9d4b024a3102fc083c925c242d98ac27b1c5f6 is the first bad commit commit 4a9d4b024a3102fc083c925c242d98ac27b1c5f6 Author: Al Viro Date: Sun Jun 24 09:56:45 2012 +0400 switch fput to task_work_add ... and schedule_work() for interrupt/kernel_thread callers (and yes, now it *is* OK to call from interrupt). We are guaranteed that __fput() will be done before we return to userland (or exit). Note that for fput() from a kernel thread we get an async behaviour; it's almost always OK, but sometimes you might need to have __fput() completed before you do anything else. There are two mechanisms for that - a general barrier (flush_delayed_fput()) and explicit __fput_sync(). Both should be used with care (as was the case for fput() from kernel threads all along). See comments in fs/file_table.c for details.
