* [PATCH] read_mapping_page for address spacePekka Enberg2006-06-231-4/+2
| | | | | | | | | | Add read_mapping_page() which is used for callers that pass mapping->a_ops->readpage as the filler for read_cache_page. This removes some duplication from filesystem code.

* [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen2006-01-091-2/+2
| | | | | | | | | | | | | This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.

* NTFS: Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocksAnton Altaparmakov2005-10-041-1/+3
| | | | | | | | which is zero for a resident attribute but should no longer be zero once the attribute is non-resident as it then has real clusters allocated. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
* NTFS: Change ntfs_attr_make_non_resident to take the attribute value sizeAnton Altaparmakov2005-10-041-3/+10
| | | | | | | | | | as an extra parameter. This is needed since we need to know the size before we can map the mft record and our callers always know it. The reason we cannot simply read the size from the vfs inode i_size is that this is not necessarily uptodate. This happens when ntfs_attr_make_non_resident() is called in the ->truncate call path.

* NTFS: - Change ntfs_cluster_alloc() to take an extra boolean parameterAnton Altaparmakov2005-10-041-9/+1

| | | | | | | | | | | - Fix a bug in ntfs_map_runlist_nolock() where we forgot to protect access to the allocated size in the ntfs inode with the size lock. - Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to return LCN_ENOENT when there is no runlist and the allocated size is zero. - Fix load_attribute_list() to handle the case of a NULL runlist.

Otherwise we get into problems when we try to map an out of bounds vcn because we then try to map the already mapped runlist fragment which causes ntfs_mapping_pairs_decompress() to fail and return error.

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!
