For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.

This\nallows it to use userspace cluster stacks and fs/dlm. This commit\nforces o2cb for now. A latter commit will bump the protocol version and\nallow non-o2cb stacks.\n\nThis is one big sed, really. LKM_xxMODE becomes DLM_LOCK_xx. LKM_flag\nbecomes DLM_LKF_flag.\n\nWe also learn to check that the LVB is valid before reading it. Any DLM\ncan lose the contents of the LVB during a complicated recovery. userdlm\nshould be checking this. Now it does. dlmfs will return 0 from read(2)\nif the LVB was invalid.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n" }, { "commit": "e8fce482f3702c1ad27c97b26db5022aa1fa64c7", "tree": "053d990d2e20a569021b2037a993700a58bc83e2", "parents": [ "553b5eb91abd5f8e679d23ae547b92c589726814" ], "author": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Tue Feb 09 17:52:13 2010 -0800" }, "committer": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Fri Feb 26 15:41:18 2010 -0800" }, "message": "ocfs2_dlmfs: Don\u0027t honor truncate.
