2008-12-03UBIFS: avoid unnecessary checksKukkonen Mika
I have a habit of compiling kernel with EXTRA_CFLAGS="-Wextra -Wno-unused -Wno-sign-compare -Wno-missing-field-initializers" and so fs/ubifs/key.h give lots (~10) of these every time: CC fs/ubifs/tnc_misc.o In file included from fs/ubifs/ubifs.h:1725, from fs/ubifs/tnc_misc.c:30: fs/ubifs/key.h: In function 'key_r5_hash': fs/ubifs/key.h:64: warning: comparison of unsigned expression >= 0 is always true fs/ubifs/key.h: In function 'key_test_hash': fs/ubifs/key.h:81: warning: comparison of unsigned expression >= 0 is always true This patch fixes the warnings.

2008-09-30UBIFS: add bulk-read facilityAdrian Hunter
Some flash media are capable of reading sequentially at faster rates. UBIFS bulk-read facility is designed to take advantage of that, by reading in one go consecutive data nodes that are also located consecutively in the same LEB. Read speed on Arm platform with OneNAND goes from 17 MiB/s to 19 MiB/s. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
