This isn\u0027t\nreally reliable but used to be the best that could be done\ndue to deadlock potential of waiting for the entire flush.\n\nNow the inode flush is safe to execute while we hold page\nand inode locks, we can wait for all the inodes to flush\nsynchronously. Convert the wait mechanism to a completion\nto do this efficiently. This should remove all remaining\nspurious ENOSPC errors from the delayed allocation reservation\npath.\n\nThis is extracted almost line for line from a larger patch\nfrom Mikulas Patocka.\n\nSigned-off-by: Mikulas Patocka \u003cmpatocka@redhat.com\u003e\nSigned-off-by: Dave Chinner \u003cdavid@fromorbit.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "5825294edd3364cbba6514f70d88debec4f6cec7", "tree": "5462388cdb6b36b2f0f1cf75dc6ee60a7c643a23", "parents": [ "a8d770d987ee20b59fba6c37d7f0f2a351913c4b" ], "author": { "name": "Dave Chinner", "email": "david@fromorbit.com", "time": "Mon Apr 06 18:45:44 2009 +0200" }, "committer": { "name": "Christoph Hellwig", "email": "hch@brick.lst.de", "time": "Mon Apr 06 18:45:44 2009 +0200" }, "message": "xfs: make inode flush at ENOSPC synchronous\n\nWhen we are writing to a single file and hit ENOSPC, we trigger a background\nflush of the inode and try again. Because we hold page locks and the iolock,\nthe flush won\u0027t proceed until after we release these locks. This occurs once\nwe\u0027ve given up and ENOSPC has been reported. Hence if this one is the only\ndirty inode in the system, we\u0027ll get an ENOSPC prematurely.\n\nTo fix this, remove the async flush from the allocation routines and move\nit to the top of the write path where we can do a synchronous flush\nand retry the write again. Only retry once as a second ENOSPC indicates\nthat we really are ENOSPC.\n\nThis avoids a page cache deadlock when trying to do this flush synchronously\nin the allocation layer that was identified by Mikulas Patocka.\n\nSigned-off-by: Dave Chinner \u003cdavid@fromorbit.com\u003e\nReviewed-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "a8d770d987ee20b59fba6c37d7f0f2a351913c4b", "tree": "3da37edba537ca5860eae97f47fb1204bc5a55b3", "parents": [ "9d7fef74b23fe57803c5f71fab11630d9ec2cb4b" ], "author": { "name": "Dave Chinner", "email": "david@fromorbit.com", "time": "Mon Apr 06 18:44:54 2009 +0200" }, "committer": { "name": "Christoph Hellwig", "email": "hch@brick.lst.de", "time": "Mon Apr 06 18:44:54 2009 +0200" }, "message": "xfs: use xfs_sync_inodes() for device flushing\n\nCurrently xfs_device_flush calls sync_blockdev() which is\na no-op for XFS as all it\u0027s metadata is held in a different\naddress to the one sync_blockdev() works on.\n\nCall xfs_sync_inodes() instead to flush all the delayed\nallocation blocks out.
