dentry/dcache considerations
----------
+----------------------------
Currently, in casefolded directories, bcachefs (like other filesystems) will not cache
negative dentry's.
This is because currently doing so presents a problem in the following scenario:
+
- Lookup file "blAH" in a casefolded directory
- Creation of file "BLAH" in a casefolded directory
- Lookup file "blAH" in a casefolded directory
+
This would fail if negative dentry's were cached.
This is slightly suboptimal, but could be fixed in future with some vfs work.
