[PATCH 2/4] Rename ramzswap files to zram

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

 



Related changes:
 - Modify revelant Kconfig and Makefile accordingly.
 - Change include filenames in code.
 - Remove dependency on CONFIG_SWAP in Kconfig as zram usage
is no longer limited to swap disks.
