we should free just the allocated blocks. Signed-off-by: Alex Tomas <alex@clusterfs.com> Signed-off-by: Mingming Cao <cmm@us.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2007-05-31ext4: Extent overlap bugfixAmit Arora
This patch adds a check for overlap of extents and cuts short the new extent to be inserted, if there is a chance of overlap. Signed-off-by: Amit Arora <aarora@in.ibm.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

Fix a nit in ext4_ext_calc_credits_for_insert(). Besides, credits for the new root are already added in the index split accounting.

2006-10-11[PATCH] ext4: removesector_t bits checkMingming Cao
Previously when in-kernel ext4 block type is sector_t, it's only 4 bits long under some 32bit arch (when CONFIG_LBD is not on). So we need to check the size of sector_t before we read 48bit long on-disk blocks to in-kernel blocks. These checks are unnecessary now as we changed the in-kernel blocks to unsigned longlong.

2006-10-11[PATCH] ext4: uninitialised extent handlingSuparna Bhattacharya
Make it possible to add file preallocation support in future as an RO_COMPAT feature by recognizing uninitialized extents as holes and limiting extent length to keep the top bit of ee_len free for marking uninitialized extents.
