Andreas Kling	8adadf8a46	FileSystem: Reuse existing custodies when possible, and keep them updated. ... Walk the custody cache and try to reuse an existing one when possible. The VFS is responsible for updating them when something happens that would cause the described relationship to change. This is definitely not perfect but it does work for the basic scenarios like renaming and removing directory entries.	2019-05-31 15:22:52 +02:00
Andreas Kling	393851418b	FileSystem: Port most of the code over to using custodies. ... The current working directory is now stored as a custody. Likewise for a process executable file. This unbreaks /proc/PID/fd which has not been working since we made the filesystem bigger. This still needs a bunch of work, for instance when renaming or removing a file somewhere, we have to update the relevant custody links.	2019-05-30 18:58:59 +02:00
Andreas Kling	4cb87b1753	FileSystem: Add a Custody class that represents a parent/child guardianship. ... A custody is kind of a directory entry abstraction that represents a single entry in a parent directory that tells us the name of a child inode. The idea here is for path resolution to produce a chain of custody objects.	2019-05-30 17:46:08 +02:00
