A patch description would be useful here; the cover letter wouldn't be
checked in.
Yeah. Please hote the RFC.
I was really hoping for some broader feedback about whether this
is a better approach than the more specialized ext4 extent cache.
If I can get an ack on the approach, I think a minimal block
device cache would support at least 2 or 4 entries, and I'd
need to be able to answer the questions from your other
response:
Do you have any stats on how many operations this saves for typical FS
operations such as:
- Partition table type identification (with various types such as MBR/DOS, GPT,
...)
- Partition enumeration
- Filesystem identification (with various filesystems such as FAT, ext, ...)
- File reads
Should I interpret this as support of a small(ish) block device cache?
Conceptually I think it sounds OK provided it yields some demonstrable
improvement across a variety of use-cases, and the design doesn't
prevent it addressing obvious other cases it should address.
You probably want to Cc (or hope they see this and provide feedback
anyway) a few other people such as Tom Rini, Simon Glass, Marek Vasut, etc.
