Dave Chinner ee58abdfcc xfs: avoid getting stuck during async inode flushes ... When the underlying inode buffer is locked and xfs_sync_inode_attr() is doing a non-blocking flush, xfs_iflush() can return EAGAIN. When this happens, clear the error rather than returning it to xfs_inode_ag_walk(), as returning EAGAIN will result in the AG walk delaying for a short while and trying again. This can result in background walks getting stuck on the one AG until inode buffer is unlocked by some other means. This behaviour was noticed when analysing event traces followed by code inspection and verification of the fix via further traces.
