[PATCH 5.15 028/203] ext4: allow to find by goal if EXT4_MB_HINT_GOAL_ONLY is set

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kemeng Shi <shikemeng@xxxxxxxxxxxxxxx>

[ Upstream commit 01e4ca29451760b9ac10b4cdc231c52150842643 ]

If EXT4_MB_HINT_GOAL_ONLY is set, ext4_mb_regular_allocator will only
allocate blocks from ext4_mb_find_by_goal. Allow to find by goal in
ext4_mb_find_by_goal if EXT4_MB_HINT_GOAL_ONLY is set or allocation
with EXT4_MB_HINT_GOAL_ONLY set will always fail.

EXT4_MB_HINT_GOAL_ONLY is not used at all, so the problem is not
found for now.
