2.6.10 Fix O_SYNC speedup for generic_file_write_nolock patch
I've verified this by running "verify-data" (http://people.redhat.com/sct/src/verify-data/) in write-once O_SYNC mode against a block device, forcing a reboot halfway and recording how far the write proceeded, then doing a verify-data read to check that the data that far is genuinely uptodate on disk. Without the patch, this fails: the actual write progress on disk is several 10s of MB behind the progress of the writing task. With the patch, the writing proceeds correctly as the task proceeds. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2005-514.html |
