There is probably a deadlock between the page lock and GFS\u0027 locks under\n certain combinations of mmap and fs operation I/O.\n 5. Issue relating to ref counting on internally used inodes causes a hang\n on umount (discovered before this patch, and not fixed by it)\n 6. One part of the directory metadata is different from GFS1 and will need\n to be resolved before next release.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "b381beadee8a3d6e690d30bdccddd08ab024945e", "tree": "408f4a84f3f6261c98d74b606a7ce87ffe10fa2c", "parents": [ "aa6a85a971065b013a71a399c3fc4312e2dd81eb" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jan 30 08:47:14 2006 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jan 30 08:47:14 2006 +0000" }, "message": "[GFS2] Remove unused file resize.c\n\nThe code in this file is no longer used as the rindex file is\nnow accessible to userspace, so can be read/written directly.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "a8f2d64728d8b706392fc1cb0f2fd6852a5e27ae", "tree": "ec65966590fa1be3d10491de5876850a0a3bbcbe", "parents": [ "29b7998d887529eca1ef43c8ca7b278448dc983c" ], "author": { "name": "David Teigland", "email": "teigland@redhat.com", "time": "Tue Jan 17 08:36:49 2006 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Tue Jan 17 08:36:49 2006 +0000" }, "message": "[GFS2] Fix typo in GFS2 Makefile\n\nA two line fix to the GFS2 Makefile.\n\nSigned-off-by: David Teigland \u003cteigland@redhat.com\u003e\nSigned-off-by: Steve Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "b3b94faa5fe5968827ba0640ee9fba4b3e7f736e", "tree": "70bd6068b050d2c46e338484f8b03fae4365c6c3", "parents": [ "f7825dcf8c7301cfd3724eb40c5b443cc85ab7b8" ], "author": { "name": "David Teigland", "email": "teigland@redhat.com", "time": "Mon Jan 16 16:50:04 2006 +0000" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jan 16 16:50:04 2006 +0000" }, "message": "[GFS2] The core of GFS2\n\nThis patch contains all the core files for GFS2.\n\nSigned-off-by: David Teigland \u003cteigland@redhat.com\u003e\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" } ] }
