If the specified dentry has the specified inode number, the kernel will\nunhash it.\n\nThe current \u0027fuse_notify_inval_entry\u0027 does not cause the kernel to clean up\ndirectories that are in use properly, and as a result the users of those\ndirectories see incorrect semantics from the file-system. The error condition\nseen when \u0027fuse_notify_inval_entry\u0027 is used to notify of a deleted directory is\navoided when \u0027fuse_notify_delete\u0027 is used instead.\n\nThe following scenario demonstrates the difference:\n1. User A chdirs into \u0027testdir\u0027 and starts reading \u0027testfile\u0027.\n2. User B rm -rf \u0027testdir\u0027.\n3. User B creates \u0027testdir\u0027.\n4.

As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations.
