...s DAX. If device mapper consists of both synchronous and asynchronous dax devices, we don't set 'DAXDEV_SYNC' flag. 'dm_table_supports_dax' is refactored to pass 'iterate_devices_fn' as argument so that the callers can pass the appropriate functions.

Hello, I have a problem with directories that contain more than 10000 entries (Ubuntu 8.04.1) or with more than 70000 entries (RHEL 5.2). If you use readdir(3) or readdir64(3) you get one entry twice, with same name and inode. Some analyzing showed that disabling dir_index solves this problem, but I think that this is a bug in the ext3 code, as no other file-system shows this behavior.

Hi All, As I have notified before, The 1st Linux IO controller Mini-Summit will be held in Tokyo Japan on Oct 17 -- day before the 9th Linux kernel summit. So I would like to propose the following topics for the mini-summit and discuss about them. - Multiple IO controller development projects - There are two activities for the development of IO controller, Vivek's io-controller and

Hi Dan, This series has only change in patch 2 for linux-next build failure. There is no functional change. Keeping all the existing review/acks and reposting the patch series for merging via libnvdimm tree. --- This patch series has implementation for "virtio pmem". "virtio pmem" is fake persistent memory(nvdimm) in guest which allows to bypass the guest page
