Some small cleanup and adjustments proposed by Andreas. There are two noticeable changes though: * you can now mount with inititable=n option, where n is a number which be used as wait multiplier for thread scheduling purposes (see patch #3). * introduced sysfs interface for advertising features like lazy itable initialization, to user space (see patch #6) Thanks for review! -Lukas --- [PATCH 1/6] Add helper function for blkdev_issue_zeroout [PATCH 2/6] Add inititable/noinititable mount options for ext4 [PATCH 3/6] Add inode table initialization code for Ext4 [PATCH 4/6] Use sb_issue_zeroout in setup_new_group_blocks [PATCH 5/6] Use sb_issue_discard in ext4_ext_zeroout [PATCH 6/6] Add interface to advertise ext4 features in sysfs fs/ext4/ext4.h | 44 +++++ fs/ext4/extents.c | 68 +------ fs/ext4/ialloc.c | 116 ++++++++++++ fs/ext4/resize.c | 44 +---- fs/ext4/super.c | 490 +++++++++++++++++++++++++++++++++++++++++++++++- include/linux/blkdev.h | 8 + 6 files changed, 671 insertions(+), 99 deletions(-)
