Currently reservation code assumes a bitmap given to it is all one contigous
chunk. This patch enhances it to handle a discontigous chunks. It adds new
fields m_bitmap_ext_cnt and m_bitmap_ext_arr. m_bitmap_ext_arr tracks the sizes
of each contigous free bits and m_bitmap_ext_cnt trackes number of
Current local alloc handles single contiguous free chunk of clusters. This
patch enhances local alloc to handle discontigous free chunks. It adds a new
ocfs2_local_alloc_rec structure which tracks single contiguous free chunk. An
array of these sit in the bitmap itself and track discontiguous
Hi all,
can you please review following 3 patches that implement discontiguous
localalloc bitmap support for ocfs2 file system. This feature helps
applications that significantly fragment the filesystem.
These fixes needs changes to ocfs2 tools as well. I am sending those patches
for review
This patch adds supporting functions and modifies localalloc code to implement
discontiguous localalloc bitmap.
