[f2fs-dev] [PATCH] f2fs: try to allocate sections from zoned area except file pinning

[Daeho Jeong]

From: Daeho Jeong <daehojeong@google.com>

We don't need to allocate blocks sequentially out of the section
boundary. Instead of that, try to allocate sections from zoned area as
many as possible, since conventional area should be used for file
pinning.
