fix cache coherence issues with bounce buffers

2011-07-22T13:37:30+00:00

[Rabin VINCENT] This is for I$-D$ coherence issues when bounce buffers are used for the MMC driver and code is executed from a file system on eMMC. IMO a better fix is to either change flush_kernel_dcache_page() to flush the D$ even on VIPT non-aliasing caches or to replace the flush_kernel_dcache_page() in lib/scatterlist.c with flush_dcache_page().

vfs: drop conditional inode prefetch in __do_lookup_rcu

2011-07-21T18:01:42+00:00

It seems to hurt performance in real life. Yes, the inode will be used later, but the conditional doesn't seem to predict all that well (negative dentries are not uncommon) and it looks like the cost of prefetching is simply higher than depending on the cache doing the right thing. As usual. Signed-off-by: Linus Torvalds

FS-Cache: Fix __fscache_uncache_all_inode_pages()'s outer loop

2011-07-21T17:59:16+00:00

The compiler, at least for ix86 and m68k, validly warns that the comparison: next <= (loff_t)-1 is always true (and it's always true also for x86-64 and probably all other arches - as long as pgoff_t isn't wider than loff_t). The intention appears to be to avoid wrapping of "next", so rather than eliminating the pointless comparison, fix the loop to indeed get exited when "next" would otherwise wrap. On m68k the following warning is observed: fs/fscache/page.c: In function '__fscache_uncache_all_inode_pages': fs/fscache/page.c:979: warning: comparison is always false due to limited range of data type Reported-by: Geert Uytterhoeven Reported-by: Jan Beulich Signed-off-by: Jan Beulich Signed-off-by: David Howells Cc: Suresh Jayaraman Cc: Geert Uytterhoeven Cc: stable@kernel.org Signed-off-by: Linus Torvalds

fs/libfs.c: fix simple_attr_write() on 32bit machines

2011-07-20T05:09:30+00:00

Assume that /sys/kernel/debug/dummy64 is debugfs file created by debugfs_create_x64(). # cd /sys/kernel/debug # echo 0x1234567812345678 > dummy64 # cat dummy64 0x0000000012345678 # echo 0x80000000 > dummy64 # cat dummy64 0xffffffff80000000 A value larger than INT_MAX cannot be written to the debugfs file created by debugfs_create_u64 or debugfs_create_x64 on 32bit machine. Because simple_attr_write() uses simple_strtol() for the conversion. To fix this, use simple_strtoll() instead.
