| * UBIFS: fix bulk-read handling uptodate pagesAdrian Hunter2008-09-30
| | | | | | | | | | | | | | | | 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>
| * UBIFS: improve garbage collectionAdrian Hunter2008-09-30
| | | | | | | | | | | | | | | | | | Make garbage collection try to keep data nodes from the same inode together and in ascending order. This improves performance when reading those nodes especially when bulk-read is used. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
| * UBIFS: allow for sync_fs when read-onlyAdrian Hunter2008-09-30
| | | | | | | | | | | | | | | | sync_fs can be called even if the file system is mounted read-only. Ensure the commit is not run in that case. Reported-by: Zoltan Sogor <weth@inf.u-szeged.hu> Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>

| * UBIFS: fix races in bit-fieldsArtem Bityutskiy2008-09-30
| | | | | | | | | | | | | | | | | | | | We cannot store bit-fields together if the processes which change them may race, unless we serialize them. Thus, move the nospc and nospc_rp bit-fields eway from the mount option/constant bit-fields, to avoid races. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| | | | | | | | | | | | The comparison was working, but more by accident than design. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
| * UBIFS: use bit-fields when possibleArtem Bityutskiy2008-09-30
| | | | | | | | | | | | | | | | | | The "bulk_read" and "no_chk_data_crc" have only 2 values - 0 and 1. We already have bit-fields in corresponding data structers, so make "bulk_read" and "no_chk_data_crc" bit-fields as well. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * UBIFS: check data CRC when in error stateArtem Bityutskiy2008-09-30
| | | | | | | | | | | | | | When UBIFS switches to R/O mode because of an error, it is reasonable to enable data CRC checking. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * UBIFS: improve znode splitting rulesAdrian Hunter2008-09-30
| | | | | | | | | | | | | | | | | | When inserting into a full znode it is split into two znodes. Because data node keys are usually consecutive, it is better to try to keep them together. This patch does a better job of that. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
| * UBIFS: add no_chk_data_crc mount optionAdrian Hunter2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | UBIFS read performance can be improved by skipping the CRC check when data nodes are read. This option can be used if the underlying media is considered to be highly reliable. Note that CRCs are always checked for metadata. Read speed on Arm platform with OneNAND goes from 19 MiB/s to 27 MiB/s with data CRC checking disabled. Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com>
| * UBIFS: add bulk-read facilityAdrian Hunter2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | 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>
| * UBIFS: use an IS_ERR test rather than a NULL testJulien Brunel2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of error, the function kthread_create returns an ERR pointer, but never returns a NULL pointer. So a NULL test that comes before an IS_ERR test should be deleted. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match_bad_null_test@ expression x, E; statement S1,S2; @@ x = kthread_create(...) ... when != x = E * if (x == NULL) S1 else S2 // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * UBIFS: inline one-line functionsArtem Bityutskiy2008-09-30
| | | | | | | | | | | | | | | | | | | | | | 'ubifs_get_lprops()' and 'ubifs_release_lprops()' basically wrap mutex lock and unlock. We have them because we want lprops subsystem be separate and as independent as possible. And we planned better locking rules for lprops. Anyway, because they are short, it is better to inline them.

| * UBIFS: remove unneeded unlikely()Hirofumi Nakagawa2008-09-30
| | | | | | | | | | | | | | | | IS_ERR() macro already has unlikely(), so do not use constructions like 'if (unlikely(IS_ERR())'. Signed-off-by: Hirofumi Nakagawa <hnakagawa@miraclelinux.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * UBIFS: add a print, fix comments and more minor stuffArtem Bityutskiy2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a reserved pool size print and tweaks the prints to make them look nicer. It also fixes and cleans-up some comments. Additionally, it deletes some blank lines to make the code look a little nicer. In other words, nothing essential. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
