Great, thanks for the feedback. I've integrated your suggestions, except where commented below. >> --- a/fs/reiserfs/inode.c 2007-08-06 14:32:14.000000000 -0400 >> +++ b/fs/reiserfs/inode.c 2007-08-06 15:03:04.000000000 -0400 >> @@ -197,7 +197,7 @@ static inline void set_block_dev_mapped( >> // files which were created in the earlier version can not be longer, >> // than 2 gb >> // >> -static int file_capable(struct inode *inode, long block) >> +static int file_capable(struct inode *inode, unsigned int block) > > block is logical block number within a file, not disk block address. > It should be sector_t probably. > This has nothing to do with amount of bitmaps.

No, these weren't strictly related to the topic of the patch. It was part of the hunt for places where block numbers are handled with signed variables. On 32-bit systems, this is no different than 'int block,' which is just wrong. I'll change it to sector_t or I may split the type safety patches out and have the largefs stuff just handle the bitmap differences. >> @@ -1068,8 +1068,8 @@ static int real_space_diff(struct inode >> return bytes; >> } >> >> -static inline loff_t to_real_used_space(struct inode *inode, ulong blocks, >> - int sd_size) >> +static inline loff_t to_real_used_space(struct inode *inode, >> + unsigned int blocks, int sd_size) >> { > > The callers of to_real_used_space passes inode->i_blocks as parameter > blocks. inode->i_blocks is blkcnt_t.

Again, part of the audit, though this one can just be reverted anyway since it's a no-op. >> --- a/fs/reiserfs/journal.c 2007-08-06 14:32:14.000000000 -0400 >> +++ b/fs/reiserfs/journal.c 2007-08-06 15:09:13.000000000 -0400 >> @@ -219,11 +219,12 @@ static void allocate_bitmap_nodes(struct >> } >> } >> >> -static int set_bit_in_list_bitmap(struct super_block *p_s_sb, int block, >> +static int set_bit_in_list_bitmap(struct super_block *p_s_sb, >> + unsigned int block, >> struct reiserfs_list_bitmap *jb) >> { >> - int bmap_nr = block / (p_s_sb->s_blocksize << 3); >> - int bit_nr = block % (p_s_sb->s_blocksize << 3); >> + unsigned int bmap_nr = block / (p_s_sb->s_blocksize << 3); >> + unsigned int bit_nr = block % (p_s_sb->s_blocksize << 3); >> > > Maybe __u32 or b_blocknr_t? Why? It doesn't refer to block numbers at all. It's not strictly needed since we won't exceed the range of a signed int, but it's a value that can never be negative. >> @@ -2279,8 +2280,9 @@ static int journal_read_transaction(stru >> Right now it is only used from journal code.

Without the change, block is a signed int, which is wrong. OTOH, it probably won't ever be a problem since it would require the journal to be past the 8 TB boundary. I'll change it to b_blocknr_t just the same. I've split out the patches, and I'll post the series shortly. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4-svn0 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGuIwGLPWxlyuTD7IRAuckAJwLbaNYIjte9Ssd/otSYBNS75QVxACeJief 48XI/7hklkl2jkYktxaApTQ= =7aHC -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
