Subject: [PATCH v4 0/2] powerpc/pseries: Implement indexed-count hotplug memory management
Date: Mon, 1 Aug 2016 12:19:41 -0500 [thread overview]
Message-ID: <437ead25-8938-a0e8-c7cf-8ead45e5ef3b@linux.vnet.ibm.com> (raw)
Indexed-count memory management allows addition and removal of contiguous
lmb blocks with a single command. When compared to the series of calls
previously required to manage contiguous blocks, indexed-count decreases
command frequency and reduces risk of buffer overflow.
Changes in v2:
--------------
-[PATCH 1/2]: -remove potential memory leak when parsing command
-use u32s drc_index and count instead of u32 ic[]
in dlpar_memory
-[PATCH 2/2]: -use u32s drc_index and count instead of u32 ic[]
in dlpar_memory
Changes in v3:
--------------
-[PATCH 1/2]: -add logic to handle invalid drc_index input
-update indexed-count trigger to follow naming convention
-update dlpar_memory to follow kernel if-else style
-[PATCH 2/2]: -add logic to handle invalid drc_index input
Changes in v4:
--------------
-[PATCH 1/2]: -add logic to handle kstrdup failure
-add logic to handle invalid command format
