ext4: cleanup for compiling mballoc with verification and debugging #defines
From: Solofo Ramangalahy <Solofo.Ramangalahy@xxxxxxxx>
This patch allows compiling mballoc with:
#define AGGRESSIVE_CHECK
#define DOUBLE_CHECK
#define MB_DEBUG
It fixes:
Compilation errors:
fs/ext4/mballoc.c: In function '__mb_check_buddy':
fs/ext4/mballoc.c:605: error: 'struct ext4_prealloc_space' has no member named 'group_list'
fs/ext4/mballoc.c:606: error: 'struct ext4_prealloc_space' has no member named 'pstart'
fs/ext4/mballoc.c:608: error: 'struct ext4_prealloc_space' has no member named 'len'
Compilation warnings:
fs/ext4/mballoc.c: In function 'ext4_mb_normalize_group_request':
fs/ext4/mballoc.c:2863: warning: format '%lu' expects type 'long unsigned int', but argument 3 has type 'int'
fs/ext4/mballoc.c: In function 'ext4_mb_use_inode_pa':
fs/ext4/mballoc.c:3103: warning: format '%lu' expects type 'long unsigned int', but argument 3 has type 'int'
Sparse check:
fs/ext4/mballoc.c:3818:2: warning: context imbalance in 'ext4_mb_show_ac' - different lock contexts for basic block
