* score: add generic sys_call_tableArnd Bergmann2009-06-19
| | | | | | | | | | | | | | | | | | | This adds back a sys_call_table to the score architecture, which got lost in the conversion to the generic unistd.h file. It's rather worrying that the code got submitted without a system call table, which evidently means that it got zero testing. Since the system call table has a different layout from the old one (which was modeled after the mips-o32 one), I also try to fix the entry.S path to use it. In the modified calling conventions, all system call arguments are passed as registers r4 through r9, instead of r4 through r7 plus stack for the fifth and sixth argument. This matches what other architectures to when they normally pass arguments on the stack. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

| * ext4: Don't update ctime for non-extent-mapped inodesTheodore Ts'o2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The VFS handles updating ctime, so we don't need to update the inode's ctime in ext4_splace_branch() to update the direct or indirect blocks. This was harmless when we did this in ext3, but in ext4, thanks to delayed allocation, updating the ctime in ext4_splice_branch() can cause the ctime to mysteriously jump when the blocks are finally allocated. Thanks to Björn Steinbrink for pointing out this problem on the git mailing list. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

| | | | | | | | | | | | | | | | | | The function ext4_mb_free_blocks() was using an "unsigned long" to pass a block number; this will cause 64-bit block numbers to get truncated on x86 and other 32-bit platforms.

| * ext4: teach the inode allocator to use a goal inode numberAndreas Dilger2009-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhance the inode allocator to take a goal inode number as a paremeter; if it is specified, it takes precedence over Orlov or parent directory inode allocation algorithms. The extents migration function uses the goal inode number so that the extent trees allocated the migration function use the correct flex_bg. In the future, the goal inode functionality will also be used to allocate an adjacent inode for the extended attributes. Also, for testing purposes the goal inode number can be specified via /sys/fs/{dev}/inode_goal. This can be useful for testing inode allocation beyond 2^32 blocks on very large filesystems.

| * ext4: Use a hash of the topdir directory name for the Orlov parent groupTheodore Ts'o2009-06-13
| | | | | | | | | | | | | | | | | | Instead of using a random number to determine the goal parent grop for the Orlov top directories, use a hash of the directory name. This allows for repeatable results when trying to benchmark filesystem layout algorithms. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

| | | | | | | | | | | | | | | | | | | | | | We're running out of space in the mount options word, and EXT4_MOUNT_ABORT isn't really a mount option, but a run-time flag. So move it to become EXT4_MF_FS_ABORTED in s_mount_flags. Also remove bogus ext2_fs.h / ext4.h simultaneous #include protection, which can never happen. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
| * ext4: update the s_last_mounted field in the superblockTheodore Ts'o2009-06-13
| | | | | | | | | | | | | | | | | | | | | | This field can be very helpful when a system administrator is trying to sort through large numbers of block devices or filesystem images. What is stored in this field can be ambiguous if multiple filesystem namespaces are in play; what we store in practice is the mountpoint interpreted by the process's namespace which first opens a file in the filesystem.

| | | | | | | | | | | | | | | | We can only fit 32 options in s_mount_opt because an unsigned long is 32-bits on a x86 machine. So use an unsigned int to save space on 64-bit platforms. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

| * ext4: avoid unnecessary spinlock in critical POSIX ACL pathTheodore Ts'o2009-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a filesystem supports POSIX ACL's, the VFS layer expects the filesystem to do POSIX ACL checks on any files not owned by the caller, and it does this for every single pathname component that it looks up. That obviously can be pretty expensive if the filesystem isn't careful about it, especially with locking. That's doubly sad, since the common case tends to be that there are no ACL's associated with the files in question. ext4 already caches the ACL data so that it doesn't have to look it up over and over again, but it does so by taking the inode->i_lock spinlock on every lookup. Which is a noticeable overhead even if it's a private lock, especially on CPU's where the serialization is expensive (eg Intel Netburst aka 'P4'). For the special case of not actually having any ACL's, all that locking is unnecessary. Even if somebody else were to be changing the ACL's on another CPU, we simply don't care - if we've seen a NULL ACL, we might as well use it. So just load the ACL speculatively without any locking, and if it was NULL, just use it. If it's non-NULL (either because we had a cached entry, or because the cache hasn't been filled in at all), it means that we'll need to get the lock and re-load it properly.

Of course, this only matters for files you don't own (the owner never needs to do the ACL checks), but that's the common case for libraries, header files, and executables. As well as for the base components of any absolute pathname, even if you are the owner of the final file. [ At some point we probably want to move this ACL caching logic entirely into the VFS layer (and only call down to the filesystem when uncached), but in the meantime this improves ext3 a bit. A similar fix to btrfs makes a much bigger difference (15x improvement in lmbench) due to broken caching. ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Acked-by: Jan Kara <jack@suse.cz> Cc: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds in preliminary support for the SH7786 PCIe module PCI ops, and the corresponding module definitions. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | | | sh: turn off irqs when disabling CMT/TMU timersMagnus Damm2009-06-17

Only using start/stop bits is not enough. This fixes a bootup hang on Migo-R when the CMT is replaced by TMU for clockevents but the CMT keeps on delivering irqs even though the timer start bit is off.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the shared clock cpg code from bootmem to slab. Without this patch the current bootmem code triggers WARN_ON() because the slab is available. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
