  "message": "tmpfs: depend on shmem\n\nCONFIG_SHMEM off gives you (ramfs masquerading as) tmpfs, even when\nCONFIG_TMPFS is off: that\u0027s a little anomalous, and I\u0027d intended to make\nmore sense of it by removing CONFIG_TMPFS altogether, always enabling its\ncode when CONFIG_SHMEM; but so many defconfigs have CONFIG_SHMEM on\nCONFIG_TMPFS off that we\u0027d better leave that as is.\n\nBut there is no point in asking for CONFIG_TMPFS if CONFIG_SHMEM is off:\nmake TMPFS depend on SHMEM, which also prevents TMPFS_POSIX_ACL\nshmem_acl.o being pointlessly built into the kernel when SHMEM is off.\n\nAnd a selfish change, to prevent the world from being rebuilt when I\nswitch between CONFIG_SHMEM on and off: the only CONFIG_SHMEM in the\nheader files is mm.h shmem_lock() - give that a shmem.c stub instead.\n\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nAcked-by: Matt Mackall \u003cmpm@selenic.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
