agree, though seems we'd better make it blocksize-insensitive
Units? Doesn't seem to matter anyway as it's never referenced. + /* tunables */ + unsigned long s_mb_factor; + unsigned long s_stripe; + unsigned long s_mb_small_req; + unsigned long s_mb_large_req; + unsigned long s_mb_max_to_scan; + unsigned long s_mb_min_to_scan; could we get some comments here as to what these are, and what units?
OK, I'll do as well as policy (and tunning) description.
Same is true many places... for example +static int mb_find_extent(struct ext4_buddy *e3b, int order, int block, + int needed, struct ext4_free_extent *ex) how many "what" are needed?
well, blocks :)
And perhaps an addition of the new mount options to Documentation/fs/ext4.txt would be good. +#define EXT4_MB_BITMAP(e3b) ((e3b)->bd_bitmap) +#define EXT4_MB_BUDDY(e3b) ((e3b)->bd_buddy) For the sake of consistency should these (and others) be e4b?
OK
Also there are a *lot* of BUGs and BUG_ONs added in this patch... are none of these recoverable?
well, I'll review the code in this regard again, but most of them are not. not that I like kernel panics, but BUG_ON() are very helpful to maintain code, especially in long-term. thanks, Alex - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
