For example, in current 2.5, if a READA attempt is actually aborted, end_buffer_io_sync reports a "buffer I/O error". Every time. And nobody has reported this. It _is_ possible to hit this in 2.5, because of ext2_preread_inode(). Probably, also it's possible to hit it in 2.4 with hundreds of processes all issuing ext3 directory readahead. But it's pretty remote. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
