From 94deac977fbd0246c971b4f1d17a6385f5e0b1a4 Mon Sep 17 00:00:00 2001 From: Hans Holmberg Date: Mon, 1 Sep 2025 10:52:04 +0000 Subject: [PATCH] fs: add an enum for number of life time hints Add WRITE_LIFE_HINT_NR into the rw_hint enum to define the number of values write life time hints can be set to. This is useful for e.g. file systems which may want to map these values to allocation groups.
