* f2fs-utils: Fix Android host utilsstable/cm-13.0-ZNH2KBstable/cm-13.0-ZNH2KSteve Kondik2016-01-212-3/+16
| | | | | | | * __ANDROID__ isn't defined for host utils. * Additionally, use the old behavior as the fallback. Change-Id: Ic0247358fb19595a70f9dd455914bd8f3f9710e2

* Fix readonly for androidGreg Wallace2016-01-191-1/+22
| | | | | | | | | The hasmntopt() function doesn't exist in android, so it needs to be defined if we are building for android. Also, MNTOPT_RO isn't defined on android (and maybe others), so we need to manually specify if if it isn't already defined. Change-Id: I55330e37cebc087e138cdf6a0cbbe61df59f55fa

* fsck.f2fs: fix losing journal entriesJaegeuk Kim2016-01-191-1/+4
| | | | | | | | | | | If fsck.f2fs reports a bug, move_curseg_info tries to change the current segment info. When it changes the new summary block, it overwrites the existing journal entries. This patch fixes it not to overwrite journal entry space. Change-Id: I99e118eb0e97985348fef212d0fff6b7a161b3a3 Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
* defrag.f2fs: fix missing SSA updatesJaegeuk Kim2016-01-191-3/+6
| | | | | | | | | | | Previously SSA is updated if it is not included in current segment info. But, defrag.f2fs doesn't handle current segment info during the process, and instead lastly update the whole current segment info at a time. So, we need to update summary entries all the time. Otherwise, we can lose the SSA entry. Change-Id: Ic94dc3b3b589620d30c7c442ec2b580ce4c76cad Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

* mkfs.f2fs: fix to calculate left space of checkpoint page correctlyChao Yu2016-01-191-1/+1
| | | | | | | | | | | | | We reserved one segment for NAT region at least, so when formatting fs, calculated maximum size of left space in CP page should be: CHECKSUM_OFFSET - sizeof(struct f2fs_checkpoint) + 1 - 64 (size of reserved NAT bitmap). Fix the incorrect calculated size to avoid potential overflow bug here.

* defrag.f2fs: introduce defragmentation toolJaegeuk Kim2016-01-198-9/+538
| | | | | | | | | | | | | | | | | | | | | This tool tries to move the valid blocks ranging from blkaddr to blkaddr + len to targeted blkaddr with a direction like expand or shrink. The option includes: -d debug level [default:0] -s start block address [default: main_blkaddr] -l length [default:512 (2MB)] -t target block address [default: main_blkaddr + 2MB] -i set direction as shrink [default: expand] For example, # defrag.f2fs -s 0x100 -l 0x10 -t 0x4000 /dev/sdb1 This will move data blocks between 0x100 and 0x110 to the right side of 0x4000 space.

* f2fs-tools: add library version infoJaegeuk Kim2016-01-193-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch gives the version info for two libraries. mkfs/libf2fs_format.la lib/libf2fs.la The versioning rule should be: 1. Start with version information of '0:0:0' for each libtool library. 2. Update the version information only immediately before a public release of your software. More frequent updates are unnecessary, and only guarantee that the current interface number gets larger faster. 2. If the library source code has changed at all since the last update, then increment revision (c:r:a) becomes (c:r+1:a). 3. If any interfaces have been added, removed, or changed since the last update, increment current, and set revision to 0. 4. If any interfaces have been added since the last public release, then increment age. 5. If any interfaces have been removed or changed since the last public release, then set age to 0. quoted from: http://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html#Updating-version-info Change-Id: I2226ec841157adeb65bceda06eb2e4bcafce66a4 Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
