hfs/hfsplus: convert printks to pr_

2013-05-01T00:04:05+00:00

Use a more current logging style.

Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
hfsplus now uses "hfsplus: " for all messages.
Coalesce formats.
Prefix debugging messages too.

hfsplus: fix overflow in sector calculations in hfsplus_submit_bio

2012-06-17T21:39:45+00:00

The variable io_size was unsigned int, which caused the wrong sector number
to be calculated after aligning it. This then caused mount to fail with big
volumes, as backup volume header information was searched from a
wrong sector.

hfsplus: Fix kfree of wrong pointers in hfsplus_fill_super() error path

2011-09-15T16:03:16+00:00

Commit 6596528e391a ("hfsplus: ensure bio requests are not smaller than
the hardware sectors") changed the pointers used for volume header
allocations but failed to free the correct pointers in the error path
path of hfsplus_fill_super() and hfsplus_read_wrapper.

The second hunk came from a separate patch by Pavel Ivanov.

hfsplus: ensure bio requests are not smaller than the hardware sectors

2011-07-22T14:37:44+00:00

Currently all bio requests are 512 bytes, which may fail for media
whose physical sector size is larger than this. Ensure these
requests are not smaller than the block device logical block size.

hfsplus: lift the 2TB size limit

2011-06-30T11:40:59+00:00

Replace the hardcoded 2TB limit with a dynamic limit based on the block
size now that we have fixed the few overflows preventing operation
with large volumes.

hfsplus: fix overflow in hfsplus_read_wrapper

2011-06-30T11:40:59+00:00

For partitions larger than 2TB or at such an offset the hfs wrapper code
in hfsplus might overflow the range representable in a 32-bit
data type. Make sure we use a sector_t for the arithmetics leading to it.

I'm not sure this code can be readed at all as hfs itself never supported
such large volumes.

hfsplus: add missing call to bio_put()

2011-06-30T11:28:32+00:00

hfsplus leaks bio objects by failing to call bio_put() on the bios
it allocates. Add the missing call to fix the leak.
