hfs+: unable to access random files (after a while)

[Luc Pionchon <pionchon.luc@gmail.com>]

Hi,

my system randomly fails to access (random) files on a HFS+ partition.

Could anybody help me to identify the issue?


I have a HFS+ partition shared between Linux and OSX.
I created it with OSX Disk Utility as HFS+, Case sensitive, Not Journaled.

After "some time" the system fails to access random files.
It gives various error messages, like:
- "Error when getting information for file 'foo': Cannot allocate memory"
- "Error when getting information for file 'foo': invalid argument"
- "Error when getting information for file 'foo': input/output error"

Sometimes it is enough to unmount/remount the partition,
then it works fine again "for a while".

I am having this issue since 3.13.
It is still present in 4.1.0-rc1.
3.12.24 used to work fine.

Can it be an issue on my specific partition? Or in the driver?
OSX Disk Utility reports no issue on the partition,
and OSX Finder never complains.
fsck.hfsplus reports no issue either.

I gave more information at https://bugzilla.kernel.org/show_bug.cgi?id=78761


Could anybody help me to identify the issue?
