If the file was opened and never read the close will pass a # NULL pointer to hrtime_cancel(). # # - Rewrite of eventfs. # # Linus wrote a patch series to remove the dentry references in the # eventfs_inode and to use ref counting and more of proper VFS # interfaces to make it work. # # - Add warning to put_ei() if ei is not set to free. That means # something is about to free it when it shouldn't. # # - Restructure the eventfs_inode to make it more compact, and remove the # unused llist field. # # - Remove the fsnotify*() funtions for when the inodes were being # created in the lookup code. It doesn't make sense to notify about # creation just because something is being looked up. # # - The inode hard link count was not accurate. # # It was being updated when a file was looked up. The inodes of # directories were updating their parent inode hard link count every # time the inode was created. That means if memory reclaim cleaned a # stale directory inode and the inode was lookup up again, it would # increment the parent inode again as well. Al Viro said to just have # all eventfs directories have a hard link count of 1. That tells user # space not to trust it. # # * tag 'trace-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: # eventfs: Keep all directory links at 1 # eventfs: Remove fsnotify*() functions from lookup() #
