2006-01-10[PATCH] ntfs: remove superflous MS_NOATIME/MS_NODIRATIME assignmentsChristoph Hellwig
MS_RDONLU implies not atime updates at all, no need for the MS_NOATIME and MS_NODIRATIME flags. Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Anton Altaparmakov <aia21@cantab.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-01-10[PATCH] replace inode_update_time with file_update_timeChristoph Hellwig
To allow various options to work per-mount instead of per-sb we need a struct vfsmount when updating ctime and mtime. This preparation patch replaces the inode_update_time routine with a file_update_atime routine so we can easily get at the vfsmount. (and the file makes more sense in this context anyway). Also get rid of the unused second argument - we always want to update the ctime when calling this routine.

2006-01-09[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen
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.

Minor tidying. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-11NTFS: The big ntfs write(2) rewrite has arrived. We now implement our ownAnton Altaparmakov
file operations ->write(), ->aio_write(), and ->writev() for regular files. This replaces the old use of generic_file_write(), et al and the address space operations ->prepare_write and ->commit_write. This means that both sparse and non-sparse (unencrypted and uncompressed) files can now be extended using the normal write(2) code path. There are two limitations at present and these are that we never create sparse files and that we only have limited support for highly fragmented files, i.e. ones whose data attribute is split across multiple extents. When such a case is encountered, EOPNOTSUPP is returned. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.

2005-10-04NTFS: Enable ATTR_SIZE attribute changes in ntfs_setattr(). This completesAnton Altaparmakov
the initial implementation of file truncation. Now both open(2)ing a file with the O_TRUNC flag and the {,f}truncate(2) system calls will resize a file appropriately. The limitations are that only uncompressed and unencrypted files are supported. Also, there is only very limited support for highly fragmented files (the ones whose $DATA attribute is split into multiple attribute extents). Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04NTFS: Implement fs/ntfs/inode.[hc]::ntfs_truncate(). It only supportsAnton Altaparmakov
uncompressed and unencrypted files. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04NTFS: Add fs/ntfs/attrib.[hc]::ntfs_attr_extend_allocation(), a function toAnton Altaparmakov
extend the allocation of an attributes. Optionally, the data size, but not the initialized size can be extended, too. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04NTFS: Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocksAnton Altaparmakov
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>
2005-10-04NTFS: Change ntfs_attr_make_non_resident to take the attribute value sizeAnton Altaparmakov
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. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04NTFS: - Change ntfs_cluster_alloc() to take an extra boolean parameterAnton Altaparmakov
specifying whether the cluster are being allocated to extend an attribute or to fill a hole. - Change ntfs_attr_make_non_resident() to call ntfs_cluster_alloc() with @is_extension set to TRUE and remove the runlist terminator fixup code as this is now done by ntfs_cluster_alloc().

2005-10-04NTFS: - Change {__,}ntfs_cluster_free() to also take an optional attributeAnton Altaparmakov

2005-10-04NTFS: Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused theAnton Altaparmakov
