* NTFS: Fix a mount time deadlock.Anton Altaparmakov2007-10-121-14/+129
| | | | | | | | | | | | | | | | | | | | | | Big thanks go to Mathias Kolehmainen for reporting the bug, providing debug output and testing the patches I sent him to get it working. The fix was to stop calling ntfs_attr_set() at mount time as that causes balance_dirty_pages_ratelimited() to be called which on systems with little memory actually tries to go and balance the dirty pages which tries to take the s_umount semaphore but because we are still in fill_super() across which the VFS holds s_umount for writing this results in a deadlock. We now do the dirty work by hand by submitting individual buffers. This has the annoying "feature" that mounting can take a few seconds if the journal is large as we have clear it all. One day someone should improve on this by deferring the journal clearing to a helper kernel thread so it can be done in the background but I don't have time for this at the moment and the current solution works fine so I am leaving it like this for now.

* [PATCH] bitops: ntfs: remove generic_ffs()Akinobu Mita2006-03-261-2/+2
| | | | | | | | | | Now the only user who are using generic_ffs() is ntfs filesystem. This patch isolates generic_ffs() as ntfs_ffs() for ntfs.

* NTFS: Support more clean journal ($LogFile) states.Anton Altaparmakov2005-09-081-115/+136
| | | | | | | | | | | | | | | - Support journals ($LogFile) which have been modified by chkdsk. This means users can boot into Windows after we marked the volume dirty. The Windows boot will run chkdsk and then reboot. The user can then immediately boot into Linux rather than having to do a full Windows boot first before rebooting into Linux and we will recognize such a journal and empty it as it is clean by definition. - Support journals ($LogFile) with only one restart page as well as journals with two different restart pages. We sanity check both and either use the only sane one or the more recent one of the two in the case that both are valid. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
