If it\u0027s set too large then this\ncast makes it a negative number and generally breaks the comparison.\n\nChange s_maxbytes to be loff_t instead. That should help eliminate the\ntemptation to set it too large by making it a signed value.\n\nAlso, add a warning for couple of releases to help catch filesystems that\nset s_maxbytes too large. Eventually we can either convert this to a\nBUG() or just remove it and in the hope that no one will get it wrong now\nthat it\u0027s a signed value.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Robert Love \u003crlove@google.com\u003e\nCc: Mandeep Singh Baines \u003cmsb@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "22fe404218156328a27e66349b1175cd0baa4990", "tree": "f03f8eb0b346a6950815212a5fa86c6b7e65bd16", "parents": [ "af0d9ae811d11de8a01d6bc922c5e062be01bd7f" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Fri Sep 18 13:05:44 2009 -0700" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu Sep 24 07:47:25 2009 -0400" }, "message": "vfs: split generic_forget_inode() so that hugetlbfs does not have to copy it\n\nHugetlbfs needs to do special things instead of truncate_inode_pages().\n Currently, it copied generic_forget_inode() except for\ntruncate_inode_pages() call which is asking for trouble (the code there\nisn\u0027t trivial).

This patch makes the\ncheck strict to find out busy \"System RAM\".\n\nNote: PPC64 keeps their own walk_memory_resouce(), which walk through\nppc64\u0027s lmb informaton. Because old kclist_add() is called per lmb, this\npatch makes no difference in behavior, finally.\n\nAnd this patch removes CONFIG_MEMORY_HOTPLUG check from this function.\nBecause pfn_valid() just show \"there is memmap or not* and cannot be used\nfor \"there is physical memory or not\", this function is useful in generic\nto scan physical memory range.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nCc: Américo Wang \u003cxiyou.wangcong@gmail.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c30bb2a25fcfde6157e6154a32c14686fb0bedbe", "tree": "afa4811d46e5f9035a035b2c8c864bbb6c5af049", "parents": [ "2ef43ec772551e975a6ea7cf22b59c84955aadf9" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Sep 22 16:45:43 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:41 2009 -0700" }, "message": "kcore: add kclist types\n\nPresently, kclist_add() only eats start address and size as its arguments.\nConsidering to make kclist dynamically reconfigulable, it\u0027s necessary to\nknow which kclists are for System RAM and which are not.\n\nThis patch add kclist types as\n KCORE_RAM\n KCORE_VMALLOC\n KCORE_TEXT\n KCORE_OTHER\n\nThis \"type\" is used in a patch following this for detecting KCORE_RAM.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2ef43ec772551e975a6ea7cf22b59c84955aadf9", "tree": "9560c13bcc6deb3ee00a60f93730b248029e69bb", "parents": [ "d899bf7b55f503ba7d3d07ed27c3a37e270fa7db" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Sep 22 16:45:41 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:41 2009 -0700" }, "message": "kcore: use usual list for kclist\n\nThis patchset is for /proc/kcore.
