2008-09-30UBIFS: fix bulk-read handling uptodate pagesAdrian Hunter
Bulk-read skips uptodate pages but this was putting its array index out and causing it to treat subsequent pages as holes. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>

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>
2008-08-21UBIFS: fix zero-length truncationsArtem Bityutskiy
Always allow truncations to zero, even if budgeting thinks there is no space. UBIFS reserves some space for deletions anyway. Otherwise, the following happans: 1. create a file, and write as much as possible there, until ENOSPC 2. truncate the file, which fails with ENOSPC, which is not good.

2008-08-13UBIFS: align inode data to eightArtem Bityutskiy
UBIFS aligns node lengths to 8, so budgeting has to do the same. Well, direntry, inode, and page budgets are already aligned, but not inode data budget (e.g., data in special devices or symlinks). Do this for inode data as well. Also, add corresponding debugging checks. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-08-13UBIFS: improve debuggingArtem Bityutskiy
1. Print inode mode in some of debugging messages 2. Add few more useful assertions Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-07-26[PATCH] get rid of indirect users of namei.hAl Viro
fs.h needs path.h, not namei.h; nfs_fs.h doesn't need it at all. Several places in the tree needed direct include. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
