* Two bits are used for locking and completion notification, I_LOCK and I_SYNC.
*
- * I_DIRTY_SYNC Inode itself is dirty.
- * I_DIRTY_DATASYNC Data-related inode changes pending
+ * I_DIRTY_SYNC Inode is dirty, but doesn't have to be written on
+ * fdatasync(). i_atime is the usual cause.
+ * I_DIRTY_DATASYNC Inode is dirty and must be written on fdatasync(), f.e.
+ * because i_size changed.
* I_DIRTY_PAGES Inode has dirty pages. Inode itself may be clean.
* I_NEW get_new_inode() sets i_state to I_LOCK|I_NEW. Both
* are cleared by unlock_new_inode(), called from iget().
* being set. find_inode() uses this to prevent returning
* nearly-dead inodes.
* I_SYNC Similar to I_LOCK, but limited in scope to writeback
- * of inode dirty data. Having a seperate lock for this
+ * of inode dirty data. Having a separate lock for this
* purpose reduces latency and prevents some filesystem-
* specific deadlocks.
*
- * Q: Why does I_DIRTY_DATASYNC exist? It appears as if it could be replaced
- * by (I_DIRTY_SYNC|I_DIRTY_PAGES).
* Q: What is the difference between I_WILL_FREE and I_FREEING?
* Q: igrab() only checks on (I_FREEING|I_WILL_FREE). Should it also check on
* I_CLEAR? If not, why?
