I have applied Andre's patch from http://linuxdiskcert.org on top of linux-2.4.19-pre7. Then I applied the XFS patches for 2.4.18 (unfortunately, the XFS-enabled kernel from the SGI-CVS is at 2.4.18 also, so it doesn't contain Ande's patch).
There is one reject in include/linux/sysctl.h I don't know how to fix:
*************** *** 140,145 **** VM_PAGERDAEMON=8, /* struct: Control kswapd behaviour */ VM_PGT_CACHE=9, /* struct: Set page table cache parameters */ VM_PAGE_CLUSTER=10, /* int: set number of pages to swap together */ VM_MIN_READAHEAD=12, /* Min file readahead */ VM_MAX_READAHEAD=13 /* Max file readahead */ }; --- 140,148 ---- VM_PAGERDAEMON=8, /* struct: Control kswapd behaviour */ VM_PGT_CACHE=9, /* struct: Set page table cache parameters */ VM_PAGE_CLUSTER=10, /* int: set number of pages to swap together */ + #if defined(CONFIG_XFS_FS) || defined(CONFIG_XFS_FS_MODULE) + VM_PAGEBUF=11, /* struct: Control pagebuf parameters */ + #endif VM_MIN_READAHEAD=12, /* Min file readahead */ VM_MAX_READAHEAD=13 /* Max file readahead */ };
Can anybody who knows the XFS code please tell what the alias VM_PAGEBUF in this enumeration is used for and how I could fix this?
The original 2.4.49-pre7 code seems to define another alias for 11 in this enum: /* CTL_VM names: */ enum { VM_SWAPCTL=1, /* struct: Set vm swapping control */ VM_SWAPOUT=2, /* int: Linear or sqrt() swapout for hogs */ VM_FREEPG=3, /* struct: Set free page thresholds */ VM_BDFLUSH=4, /* struct: Control buffer cache flushing */ VM_OVERCOMMIT_MEMORY=5, /* Turn off the virtual memory safety limit */ VM_BUFFERMEM=6, /* struct: Set buffer memory thresholds */ VM_PAGECACHE=7, /* struct: Set cache memory thresholds */ VM_PAGERDAEMON=8, /* struct: Control kswapd behaviour */ VM_PGT_CACHE=9, /* struct: Set page table cache parameters */ VM_PAGE_CLUSTER=10, /* int: set number of pages to swap together */ VM_MAX_MAP_COUNT=11, /* int: Maximum number of active map areas */ VM_MIN_READAHEAD=12, /* Min file readahead */ VM_MAX_READAHEAD=13, /* Max file readahead */ };
Any hints?
Thanks for your help, Robert
