Linux-2.6.12-rc2 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.

cifs: fix cifs_uniqueid_to_ino_t not to ever return 0 Currently, when the top and bottom 32-bit words are equivalent and the host is a 32-bit arch, cifs_uniqueid_to_ino_t returns 0 as the ino_t value. All we're doing to hash the value down to 32 bits is xor'ing the top and bottom 32-bit words and that obviously results in 0 if they are equivalent. The kernel doesn't really care if it returns this value, but some userland apps (like "ls") will ignore dirents that have a zero d_ino value. Change this function to use hash_64 to convert this value to a 31 bit value and then add 1 to ensure that it doesn't ever return 0. Also, there's no need to check the sizeof(ino_t) at runtime so create two different cifs_uniqueid_to_ino_t functions based on whether BITS_PER_LONG is 64 for not.

The different codepaths (unix, legacy, normal, etc...) can fill out this struct with inode info. It can then be passed as an arg to a common set of routines to get and update inodes. Add a new cifs_iget function that uses iget5_locked to identify inodes. This will compare inodes based on the uniqueid value in a cifs_fattr struct. Rather than filling out an already-created inode, have cifs_get_inode_info_unix instead fill out cifs_fattr and hand that off to cifs_iget. cifs_iget can then properly look for hardlinked inodes. On the readdir side, add a new cifs_readdir_lookup function that spawns populated dentries. Redefine FILE_UNIX_INFO so that it's basically a FILE_UNIX_BASIC_INFO that has a few fields wrapped around it. This allows us to more easily use the same function for filling out the fattr as the non-readdir codepath.

cifs: overhaul cifs_revalidate and rename to cifs_revalidate_dentry cifs_revalidate is renamed to cifs_revalidate_dentry as a later patch will add a by-filehandle variant. Add a new "invalid_mapping" flag to the cifsInodeInfo that indicates that the pagecache is considered invalid. Add a new routine to check inode attributes whenever they're updated and set that flag if the inode has changed on the server. cifs_revalidate_dentry is then changed to just update the attrcache if needed and then to zap the pagecache if it's not valid. There are some other behavior changes in here as well. Open files are now allowed to have their caches invalidated. I see no reason why we'd want to keep stale data around just because a file is open. Also, cifs_revalidate_cache uses the server_eof for revalidating the file size since that should more closely match the size of the file on the server.

cifs: fix potential races in cifs_revalidate_mapping The handling of the CIFS_INO_INVALID_MAPPING flag is racy. It's possible for two tasks to attempt to revalidate the mapping at the same time. The first sees that CIFS_INO_INVALID_MAPPING is set. It clears the flag and then calls invalidate_inode_pages2 to start shooting down the pagecache. While that's going on, another task checks the flag and sees that it's clear. It then ends up trusting the pagecache to satisfy a read when it shouldn't. Fix this by adding a bitlock to ensure that the clearing of the flag is atomic with respect to the actual cache invalidation. Also, move the other existing users of cifs_invalidate_mapping to use a new cifs_zap_mapping() function that just sets the INVALID_MAPPING bit and then uses the standard codepath to handle the invalidation.

[PATCH] vfs: add lock owner argument to flush operation Pass the POSIX lock owner ID to the flush operation.

FUSE is one such filesystem but I think it possible that some network filesystems would need this also.

Introduce cifs_copy_file_range() The earlier changes to copy range for cifs unintentionally disabled the more common form of server side copy. The patch introduces the file_operations helper cifs_copy_file_range() which is used by the syscall copy_file_range. The new file operations helper allows us to perform server side copies for SMB2.0 and 2.1 servers as well as SMB 3.0+ servers which do not support the ioctl FSCTL_DUPLICATE_EXTENTS_TO_FILE. The new helper uses the ioctl FSCTL_SRV_COPYCHUNK_WRITE to perform server side copies. The helper is called by vfs_copy_file_range() only once an attempt to clone the file using the ioctl FSCTL_DUPLICATE_EXTENTS_TO_FILE has failed.

Linux-2.6.12-rc2 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!
