remove obsolete references to powertweak This tool hasn't been maintained in over a decade, and is pretty much useless these days. Let's pretend it never happened. Also remove a long-dead email address. Signed-off-by: Dave Jones <davej@fedoraproject.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> | 12 年前 | |
fs: add CONFIG_BUFFER_HEAD Add a new config option that controls building the buffer_head code, and select it from all file systems and stacking drivers that need it. For the block device nodes and alternative iomap based buffered I/O path is provided when buffer_head support is not enabled, and iomap needs a a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call into the buffer_head code when it doesn't exist. Otherwise this is just Kconfig and ifdef changes.

fs: port ->rename() to pass mnt_idmap Convert to struct mnt_idmap. Last cycle we merged the necessary infrastructure in 256c8aed2b42 ("fs: introduce dedicated idmap type for mounts"). This is just the conversion to struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevent on the mount level. Especially for non-vfs developers without detailed knowledge in this area this can be a potential source for bugs. Once the conversion to struct mnt_idmap is done all helpers down to the really low-level helpers will take a struct mnt_idmap argument instead of two namespace arguments. This way it becomes impossible to conflate the two eliminating the possibility of any bugs. All of the vfs and all filesystems only operate on struct mnt_idmap.

Rename superblock flags (MS_xyz -> SB_xyz) This is a pure automated search-and-replace of the internal kernel superblock flags. The s_flags are now called SB_*, with the names and the values for the moment mirroring the MS_* flags that they're equivalent to. Note how the MS_xyz flags are the ones passed to the mount system call, while the SB_xyz flags are what we then use in sb->s_flags. The script to do this was: # places to look in; re security/*: it generally should *not* be # touched (that stuff parses mount(2) arguments directly), but # there are two places where we really deal with superblock flags.

iversion: Rename make inode_cmp_iversion{+raw} to inode_eq_iversion{+raw} The function inode_cmp_iversion{+raw} is counter-intuitive, because it returns true when the counters are different and false when these are equal. Rename it to inode_eq_iversion{+raw}, which will returns true when the counters are equal and false otherwise.

affs: don't write overlarge OFS data block size fields stable inclusion from stable-v6.6.87 commit 54fd5a5b7583f1964a79e9efe02e30e97b61eb95 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID6BMS Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=54fd5a5b7583f1964a79e9efe02e30e97b61eb95 -------------------------------- [ Upstream commit 011ea742a25a77bac3d995f457886a67d178c6f0 ] If a data sector on an OFS floppy contains a value > 0x1e8 (the largest amount of data that fits in the sector after its header), then an Amiga reading the file can return corrupt data, by taking the overlarge size at its word and reading past the end of the buffer it read the disk sector into! The cause: when affs_write_end_ofs() writes data to an OFS filesystem, the new size field for a data block was computed by adding the amount of data currently being written (into the block) to the existing value of the size field. This is correct if you're extending the file at the end, but if you seek backwards in the file and overwrite _existing_ data, it can lead to the size field being larger than the maximum legal value. This commit changes the calculation so that it sets the size field to the max of its previous size and the position within the block that we just wrote up to.
