Name | Describe |
---|---|
lookup_fast | |
may_delete | Check whether we can remove a link victim from directory dir, check* whether the type of victim is right.* 1. We can't do it if dir is read-only (done in permission())* 2. We should have write and exec permissions on dir* 3 |
atomic_open | Attempt to atomically look up, create and open a file from a negative* dentry |
do_unlinkat | Make sure that the actual truncation of the file will occur outside its* directory's i_mutex. Truncate can take a long time if there is a lot of* writeout happening, and we don't want to prevent access to the directory* while waiting on the I/O. |
do_renameat2 | |
d_lru_add | |
d_lru_del | |
d_lru_isolate | These can only be called under the global LRU lock, ie during the* callback for freeing the LRU list. "isolate" removes it from the* LRU lists entirely, while shrink_move moves it to the indicated* private list. |
