[merged] mm-zswap-change-incorrect-strncmp-use-to-strcmp.patch removed from -mm tree

[akpm]

The patch titled
     Subject: mm/zswap: change incorrect strncmp use to strcmp
has been removed from the -mm tree.  Its filename was
     mm-zswap-change-incorrect-strncmp-use-to-strcmp.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm/zswap: change incorrect strncmp use to strcmp

Change the use of strncmp in zswap_pool_find_get() to strcmp.

The use of strncmp is no longer correct, now that zswap_zpool_type is not
an array; sizeof() will return the size of a pointer, which isn't the
right length to compare.  We don't need to use strncmp anyway, because the
existing params and the passed in params are all guaranteed to be null
terminated, so strcmp should be used.
