[PATCH] mm/shmem: remove unneeded assignments in shmem_get_folio_gfp()

From: Lukas Bulwahn
Date: Fri Oct 07 2022 - 04:51:21 EST


After the rework of shmem_get_folio_gfp() to use a folio, the local
variable hindex is only needed to be set once before passing it to
shmem_add_to_page_cache().

Remove the unneeded initialization and assignments of the variable hindex
before the actual effective assignment and first use.

No functional change. No change in object code.
