. Added an implementation of posix_fadvise().
This can be used for providing the kernel hints about desired readahead
patterns, and for launching asynchronous readahead (what sys_readahead
does).
But its main application is for program-directed freeing of pagecache
against large streamed files. This is what O_STREAMING gives, only
posix_fadvise() is harder to use, less efficient and standards-based.
There is a test app in
http://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz
. The direct-to-BIO readahead for reiserfs works fine.
. Ported one of Andrea's -aa patches into 2.5: merging of file-backed VMAs.
Changes since 2.5.56-mm1:
-rbtree-iosched.patch
-deadline-fixes.patch
-deadline-sysfs-fix.patch
-pentium-II.patch
Merged
+deadline-np.patch
Another I/O scheduler tweak from Nick. This solves some potential
read-starves-read problems and may provide decreased latencies for some
workloads.
+saner-readahead.patch
Be smarter about how much readahead the user may start.
+fadvise.patch
Implement posix_fadvise64().
+honour-vm_reserved.patch
This shouldn't be here.
+prune-icache-stats.patch
Add vm statistics on how much pagecache is being freed via prune_icache().
Interestingly, under some workloads, 50% of page reclaim happens here.
+vma-file-merge.patch
Merging of file-backed VMAs
+mmap-whitespace.patch
make mm/mmap.c human-readable.
+quota-lockfix.patch
+quota-offsem.patch
Quota bugfixes.
-smalldevfs.patch
