* hostfs: remove "will unlock" commentJames Hogan2013-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | A "will unlock" comment was added to hostfs in the following commit, along with a spinlock: Commit e9193059b1b3733695d5b80e667778311695aa73 ("hostfs: fix races in dentry_name() and inode_name()"). But the spinlock was subsequently removed in the following commit: Commit ec2447c278ee973d35f38e53ca16ba7f965ae33d ("hostfs: simplify locking"). Since the comment is no longer applicable, remove it.

* create_mnt_ns: unidiomatic use of list_add()Al Viro2013-05-041-1/+1
| | | | | | | | | | while list_add(A, B) and list_add(B, A) are equivalent when both A and B are guaranteed to be empty, the usual idiom is list_add(what, where), not the other way round... Not a bug per se, but only by accident and it makes RTFS harder for no good reason. Spotted-by: Rajat Sharma <fs.rajat@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* fs: remove dentry_lru_prune()Yan, Zheng2013-05-041-22/+9
| | | | | | | | | | | | | When pruning a dentry, its ancestor dentry can also be pruned. But the ancestor dentry does not go through dput(), so it does not get put on the dentry LRU. Hence associating d_prune with removing the dentry from the LRU is the wrong. The fix is remove dentry_lru_prune(). Call file system's d_prune() callback directly when pruning dentries.

* fs: Fix hang with BSD accounting on frozen filesystemJan Kara2013-05-042-1/+13
| | | | | | | | | | | | | | | When BSD process accounting is enabled and logs information to a filesystem which gets frozen, system easily becomes unusable because each attempt to account process information blocks. Thus e.g. every task gets blocked in exit. It seems better to drop accounting information (which can already happen when filesystem is running out of space) instead of locking system up. So we just skip the write if the filesystem is frozen. Reported-by: Nikola Ciprich <nikola.ciprich@linuxbox.cz> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dave Hansen reported strange utime/stime values on his system: https://lkml.org/lkml/2013/4/4/435 This happens because prev->stime value is bigger than rtime value. Root of the problem are non-monotonic rtime values (i.e. current rtime is smaller than previous rtime) and that should be debugged and fixed. But since problem did not manifest itself before commit 62188451f0d63add7ad0cd2a1ae269d600c1663d "cputime: Avoid multiplication overflow on utime scaling", it should be threated as regression, which we can easily fixed on cputime_adjust() function. For now, let's apply this fix, but further work is needed to fix root of the problem.

| * sched: Do not account bogus utimeStanislaw Gruszka2013-04-301-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to rounding in scale_stime(), for big numbers, scaled stime values will grow in chunks. Since rtime grow in jiffies and we calculate utime like below: prev->stime = max(prev->stime, stime); prev->utime = max(prev->utime, rtime - prev->stime); we could erroneously account stime values as utime. To prevent that only update prev->{u,s}time values when they are smaller than current rtime.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is patch, which adds Linus's cputime scaling algorithm to the kernel. This is a follow up (well, fix) to commit d9a3c9823a2e6a543eb7807fb3d15d8233817ec5 ("sched: Lower chances of cputime scaling overflow") which commit tried to avoid multiplication overflow, but did not guarantee that the overflow would not happen. Linus crated a different algorithm, which completely avoids the multiplication overflow by dropping precision when numbers are big. It was tested by me and it gives good relative error of scaled numbers.

| * | crypto: x86/twofish-avx - use optimized XTS codeJussi Kivilinna2013-04-252-41/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change twofish-avx to use the new XTS code, for smaller stack usage and small boost to performance. tcrypt results, with Intel i5-2450M: enc dec 16B 1.03x 1.02x 64B 0.91x 0.91x 256B 1.10x 1.09x 1024B 1.12x 1.11x 8192B 1.12x 1.11x Since XTS is practically always used with data blocks of size 512 bytes or more, I chose to not make use of twofish-3way for block sized smaller than 128 bytes. This causes slower result in tcrypt for 64 bytes. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * | crypto: x86 - add more optimized XTS-mode for serpent-avxJussi Kivilinna2013-04-256-46/+273
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds AVX optimized XTS-mode helper functions/macros and converts serpent-avx to use the new facilities. Benefits are slightly improved speed and reduced stack usage as use of temporary IV-array is avoided. tcrypt results, with Intel i5-2450M: enc dec 16B 1.00x 1.00x 64B 1.00x 1.00x 256B 1.04x 1.06x 1024B 1.09x 1.09x 8192B 1.10x 1.09x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
