Category: Testcases Group: System Calls >Status: Pending >Resolution: Later Priority: 5 Private: No Submitted By: Zing Shishak (shishz) Assigned to: Nobody/Anonymous (nobody) Summary: swapon02 failure, MAX_SWAPFILES problem Initial Comment: If CONFIG_MIGRATION is set in the linux kernel, MAX_SWAPFILES is really MAX_SWAPFILES - 2. :( the failure looks like this: ./swapon02 swapon02 1 PASS : swapon(2) expected failure; Got errno - ENOENT : Path does not exist swapon02 2 PASS : swapon(2) expected failure; Got errno - EINVAL : Invalid path swapon02 0 WARN : Failed swapon for file swapfile31 returned -1 swapon02 0 WARN : Failed to turn off swap files. system reboot after execution of LTP test suite is recommended swapon02 0 WARN : Failed to turn off swap files. system reboot after execution of LTP test suite is recommended swapon02 3 BROK : Cleanup failed, quitting the test swapon02 4 BROK : Remaining cases broken swapon02 5 BROK : Remaining cases broken ---------------------------------------------------------------------- Comment By: rsalveti (rsalveti) Date: 2007-06-21 03:49 Message: Logged In: YES user_id=1269623 Originator: NO Yep, since kernel's commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0697212a411c1dae03c27845f2de2f3adb32c331 the value of MAX_SWAPFILES is depending on kernel config option CONFIG_MIGRATION. The code: /* * MAX_SWAPFILES defines the maximum number of swaptypes: things which can * be swapped to. The swap type and the offset into that swap type are * encoded into pte's and into pgoff_t's in the swapcache. Using five bits * for the type means that the maximum number of swapcache pages is 27 bits * on 32-bit-pgoff_t architectures. And that assumes that the architecture packs * the type/offset into the pte as 5/27 as well. */ #define MAX_SWAPFILES_SHIFT 5 #ifndef CONFIG_MIGRATION #define MAX_SWAPFILES (1 << MAX_SWAPFILES_SHIFT) #else /* Use last two entries for page migration swap entries */ #define MAX_SWAPFILES ((1 << MAX_SWAPFILES_SHIFT)-2) #define SWP_MIGRATION_READ MAX_SWAPFILES #define SWP_MIGRATION_WRITE (MAX_SWAPFILES + 1) #endif I don't think that there's a simple way to fix this problem. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=103382&aid=1737577&group_id=3382 ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
