[PATCH 5/5] ext4: write support for preallocated blocks/extents

This patch adds write support for preallocated (using fallocate system call) blocks/extents. The preallocated extents in ext4 are marked "uninitialized", hence they need special handling especially while writing to them. This patch takes care of that. Signed-off-by: Amit Arora <[EMAIL PROTECTED]>

[PATCH 3/5] ext4: Extent overlap bugfix

This is a fix for an extent-overlap bug. The fallocate() implementation on ext4 depends on this bugfix. Though this fix had been posted earlier, but because it is still not part of mainline code, I have attached it here too. Signed-off-by: Amit Arora <[EMAIL PROTECTED]> --- fs/ext4/extents.c

[PATCH 2/5] fallocate() on s390

This patch implements support of fallocate system call on s390(x) platform. A wrapper is added to address the issue which s390 ABI has with "preferred" ordering of arguments in this system call (i.e. int, int, loff_t, loff_t). I will request s390 experts to please review this code and verify if th

[PATCH 1/5] fallocate() implementation in i86, x86_64 and powerpc

[PATCH 0/5] fallocate system call

Based on the discussion, this new patchset uses following as the interface for fallocate() system call: asmlinkage long sys_fallocate(int fd, int mode, loff_t offset, loff_t len) It seems that only s390 architecture has a problem with such a layout of arguments in fallocate(). Thus for s390, we

ext4 online defrag (ver 0.4)

Hi all, I have made following changes to the previous online defrag patchset to improve it. Note that there is no functional change. 1. Change the handling of temporary inode. Now ext4_ext_defrag() calls ext4_new_inode()/iput() pair instead of new_inode()/delete_ext_defrag_inode(). Because

[RFC][PATCH 4/4] ext4_locality_group bug fix

Move lg_list to s_locality_dirty and mark lg as dirty if nr_to_write(total page count which has not written in disk yet) is 0 or less and lg_io is not empty in ext4_lg_sync_single_group(). This makes sure that inode is written to disk. Signed-off-by: Takashi Sato <[EMAIL PROTECTED]> --- diff -Nru
