Hi Alex, Here's the fixes I posted a few days ago with all the review comments fixed up. Version 2: - fixed typos in sector size comments - fixed setting default sector size so that the ioctl doesn't wipe it out - separate out prefetch valgrind error fix. - separate out large blkmap allocation caching fix - separate out handling of blkmap memory allocation failure during a grow to avoid a buffer overrun situation when moving extents around in the array - avoid modifying blkmap->naexts when allocation fails. - separate extent count overflow checking in blkmap allocation and growing - use #if BITS_PER_LONG == 32 - Introduce BLKMAP_NEXTS_MAX and use it unconditionally rather than open code it and only include the check on 32 bit builds - add checking for negative extent counts to avoid grow overflows past INT_MAX going undetected. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
