[PATCH v2 5/6] memblock: rename memblock_free to memblock_phys_free

Posted by Mike Rapoport 1 month, 3 weeks ago
From: Mike Rapoport <rppt@linux.ibm.com>

Since memblock_free() operates on a physical range, make its name reflect
it and rename it to memblock_phys_free(), so it will be a logical
counterpart to memblock_phys_alloc().

The callers are updated with the below semantic patch:

@@
expression addr;
expression size;
@@
- memblock_free(addr, size);
+ memblock_phys_free(addr, size);
