Trying to change the owner will fail,\nbecause fat does not know about owners or groups. chmod 0770, on the other\nhand, will succeed, even though fat does not know about the permission\ntriplet [user/group/other].\n\nSo this patch changes fat\u0027s not-quiet behavior so that only UNIX modes are\naccepted that can be mapped lossless between the fat disk format and the\nlocal system. There is only one attribute, and that is the readonly\nattribute, which is mapped to the UNIX write permission bit(s). chmod 0555\nis therefore valid (taking away the +w bits \u003c\u003d\u003e setting the readonly\nattribute). Since chmod 0775 and chmod 0755 is an ambiguous case as to\nwhether to set or clear the readonly bit, these modes are also denied.\n\nIn quiet mode, chmod and chown will continue to \"succeed\" as they did\nbefore, meaning that a subsequent stat() will temporarily return the new\nmode as long as the inode is not reread from disk, and chown will silently\ndo nothing, not even return the new uid/gid in stat().\n\nSigned-off-by: Jan Engelhardt \u003cjengelh@computergmbh.de\u003e\nCc: OGAWA Hirofumi \u003chirofumi@mail.parknet.co.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c773633916c66f8362ca01983d97bd33e35b743f", "tree": "4c3da7d614c530d851db6b3c6bcc3d85519feeb3", "parents": [ "9692bd9c140618e3f6a2848900aee96c9cd8a65c" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Tue Feb 05 14:22:58 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 14:37:15 2008 -0800" }, "message": "deprecate smbfs in favour of cifs\n\nsmbfs is a bit buggy and has no maintainer.

With a debug\npatch adding proper reverse links and stack trace logging in ext3 deployed\nin production, I found journal_stop is never run because\nmark_inode_dirty_sync is called inside release_task called by do_exit.\n(that was quite fun because I would have never thought about this\nsubtleness, I thought a regular path in ext3 had a bug and it forgot to\ncall journal_stop)\n\ndo_exit-\u003erelease_task-\u003emark_inode_dirty_sync-\u003eschedule() (will never\ncome back to run journal_stop)\n\nThe reason is that shrink_dcache_parent is racy by design (feature not\na bug) and it can do blocking I/O in some case, but the point is that\ncalling shrink_dcache_parent at the last stage of do_exit isn\u0027t safe\nfor self-reaping tasks.\n\nI guess the memory pressure of the unbalanced highmem system allowed\nto trigger this more easily.\n\nNow mainline doesn\u0027t have this line in iput (like sles9 has):\n\n \t if (inode-\u003ei_state \u0026 I_DIRTY_DELAYED)\n\t \t\t\tmark_inode_dirty_sync(inode);\n\nso it will probably not crash with ext3, but for example ext2 implements an\nI/O-blocking ext2_put_inode that will lead to similar screwups with\next2_free_blocks never coming back and it\u0027s definitely wrong to call\nblocking-IO paths inside do_exit.
